What would you suggest as an alternative to "successor" to describe these future chips?
The normally accepted definition of successor is one who replaces the one that came before it (as in succession).
The normally accepted definition of "next generation" in this field implies a new architecture (aka Core 2 to Core 3, or G4 to G5).
Kentfield and Clovertown are simply a different packaging of the Conroe and Woodcrest... putting multiple Conroe or Woodcrest chips into a multiple-chip module (MCM).
Not trying to quibble just make sure folks don't read things incorrectly.

Would be a very long keynote too:
- release date of 10.5 revealed - possibly more stuff revealed
- new software (considerable update to iWork if the rumours are true)
- iMac/MacBook updates
- iPod/iTunes stuff
And one more thing: The Auad PowerMac has been the fastest Mac until today. I present to you the new Octa Mac Pro!"

I think this speaks for itself.
When I'm working on one project, that's all my attention to it. When I'd like to encode it, I'd like my however many cores to be at full blast. Sadly, that's not happening at the moment and will remain so until they rewrite h264 encoding.
Like I said, unless people are doing what you do (sending multiple files to be encoded at the same time all the time) they won't benefit from 4, 8, 100 cores.
Now if anyone can show benchmarks that show FCP being 40-50% faster on a quad than on a dual when working on a project, I'll shut up :)
Or maybe they have?
Didn't FCP just get updated to optimize it for the Mac Pro?
I think they need the latest version over there and should rerun the test.

This would be like Ford paying Exxon a fee because some car drivers syphon gas....pretty weird!
Not quite, the car you syphon it from will still need to go back and refill... it's not duplicating the fuel....
The music industry needs a wake up call, there is probably no more complicated industry than this, with various copyright issues and loads of 'official bodies' legislating all kinds of stuff, and all because you thought of a song, recorded it with your 100 dollar acoustic guitar and want to sell it to make a living.. Try it, you can't. Once you have to go through all the above, your inspiration and will is flushed straight out....

Then that just begs the question, "why haven't these people left already?" FCP has been fairly stagnant for years. There are plenty of other alternatives, so doesn't that kinda make them fanboyish too for sticking it out when up to this point Apple has given zero hints about when or how it will take FCP to the next level?
I'm not in the video editing biz, but if the pro s/w I use in my profession hobbled my efficiency and workflow the way you are carping about FCP, and there were viable alternatives, I would abandon it quicker than pigeon can snatch a bread crumb. Just sayin'.
I'm an independent corporate video editor. Work out of the house. I've been doing NLE since 1993. I started with VideoCube, then Media 100, then Avid, and then FCP in 2001. Avid had to get really behind (and threaten to leave the mac platform) before post houses made the switch. They really screwed that up at NAB that year. They had been languishing on the mac apps and releasing certain products- Symphony, DS, etc. on Windows only for a few years and at NAB one sales guy said to someone that they would essentially be phasing out the mac platform. They denied it later, but it was probably their plan. Then FCP came out and for the corporate folks that didn't need to spend 70,000 on an Avid system, it was wonderful. In the years that followed it closed the gap immensely and Avid fought back with cheaper products and options. It became a either or situation, with FCP being the slightly cheaper option. But with the new tech in the last 2 years, Apple has to leap frog again.
But still, it's so much more than just the app. Which is why Adobe (which has all the features everyone wants in FCP) is having such a hard time getting anyone but hacks to use it. There is an installed user base and an entire generation of people trained on FCP & Avid. And it was just the above fluke that gave FCP an in. It's one thing for an individual like me to switch, but for a company that uses contractors and other companies and rely on compatibility and workflows and such, it's a nightmare. I work with independent producers, and their clients are usually large companies. All 3 of us are using FCP. If I switch, I make life hard on the producer who is cutting together rough ideas on her laptop. When we deliver product, we deliver a product and the FCP project and files so that the big company, who has editing facilites of their own, can make changes without our help in an emergency. It's part of why they feel comfortable going out of house.
It's the smaller turnkey shops that do it all in house that can afford to keep totally cutting edge and buy every upgrade. But truth is, most good editing should rely on cuts and dissolves. You need anything fancier audio or graphic wise, you should be hiring an audio professional or a graphics professional.
I have the Adobe Master collection myself because I dabble in AE, PS, Flash and Dreamweaver. But the web authoring has just gone crazy. I can't keep up with all that. And AE is starting to get that way too. For me, I would just like FCP to upgrade and/or reinvent itself so I can integrate new tech simpler. Better authoring for Blu-Ray and DVD. Better web options. Importing file formats without log and transfer BS. And lets tune it up to make it use all the processors and be a ridiculous powerhouse. High end features rivaling Avid, and the touch and elegance of Apple. Plus a few neat tricks like offline editing on iPad or using the iPad as a controller, etc. would be cool and welcome.

30 days on refurbs might mean something actually...
Any ideas?
I've always assumed that it means they've got a warehouse full of returns that they're working their way through and that they prioritise on the items they want to get shot of quickly. If correct, a longer lead time would suggest no updates due in the near future so they can take their time getting rid of the stock.
But then I'm also suspicious they ain't all returns and that they scuff the cases on all the excess stock so they can knock them out cheap without upsetting anyone.

Hehe, I remember Virginia Tech having built the 3rd fastest supercomputer out of 1100 dual powermacs G5. Back then, the XServe G5 wasn't available. You can see that in the MWSF 2004 keynote (minute 25 ff). They later switched to the Xserve G5 when those came out. It had 10.28 TF for just $5.2M.
And I remember that they were very concerned about the lack of ECC memory, and were extremely eager to replace them with Xserves as soon as the G5 model came out.

Rev D. has no overheating issues. My CPU doesn't go over 70�C when watching 1080p Flash video in fullscreen. The fan sometimes kicks in but it's still very comfortable to use on your lap, since it's barely even warm. Older MBAs suffered from overheating, that is true.
Shouldn't the flash HD have a significant role in overheating? I would think with the Flash HD with no moving parts it would be hard to over heat unless you sit there blocking the fan the whole time. :confused:

Even if that were true, so what? Apple Records was not a competitor of Apple Computer. Trademark law allows multiple companies to have the same trademark so long as they don't sell the same type of products in the same location. This is why you can have a 100 companies like "AAA Locksmith, AAA Laundry," etc. Or you can have "Hollywood Video" in Michigan being totally different than "Hollywood Video" everywhere else [interesting story that. I may have the state wrong.]
Only truly "famous" marks (e.g. Coke, McDonalds, etc.) which can be "diluted" by use with other types of products are protected against this sort of thing.
But App Store is like Coke, right? Of course it's ok if Apple does it. They've becoming one of the most hypocritical companies on the planet. Maybe Steve suffers from extreme paranoia?

I disagree. Using ATX power supplies is a stupid idea. I am sure Apple uses higher quality power supplies than you would pick up at your local CompUSA.
If they allow this there will be a lot of dead Macs, from power supplies whose rails aren't strong enough.
Not to mention those who buy the 400W model because it is only 20 bucks and drastically underpower there Mac.
This would cause to many problems. Keep it proprietary IMO.
Actually that is a good point. Another good example is how some people install incorrect RAM into their Mac - they just pick up generic cheapo RAM, not Mac-certified, and wonder why they have all sorts of issues.

I don't understand all the hype over the core 2 duo chip vs the core duo chip. They are basically the same chip. You will barely notice any difference with same speed core 2 duo over a same speed core duo.
Even when I've made big processor jumps before I've never noticed any increased performance that made a difference to me. Adding more RAM has made a massive difference though and probably would for a lot of people.

You are right. However, you try to tell consumers "Well we are moving to 2.4Ghz chips" after you just had 2.66Ghz and 3.0Ghz chips. It isnt going to work.
If today, Dell decided to move there whole line back to 1Ghz processors, nobody would buy. Unfortunetly the Ghz myth is a strong as its ever been. Taking a step backward is not an option.
It's already happened, just not in as a melodramatic way as you suggest (back to 1GHz? geez). AMD took a small step back, Hz wise when they introduced dual core, though it still advanced their "+" processor ratings I suppose that few noticed the actual clock reduction. Intel took a major step back Hz wise between Netburst and Core 2. The 5000 and 5100 series Xeon CPUs demonstrate this, you can get a Dell precision 690 with 3.73GHz Netburst based chips or the same 690 with 3.0GHz Core2 based chips.
So I don't think that a quad core Xeon running at 2.66GHz is going to be hurt too much in comparison to a dual core 3.0GHz, it's still a much more powerful processor.
Didn't you get the memo, PowerPC is dead. WTF does that have to do with anything? Do you just have this Pavlovian response to the word "Hyperthreading"?
PPC isn't dead, it's just not in new desktops anymore. IBM is making them (or at least co-designed them) for all the next generation game consoles and a lot of huge supercomputers.

Oh, we are totally getting an iPad app to go along with this program. I can feel it.
I would oh-so love the ability to down-rez a Final Cut project and send it to an iPad...do all my rough cutting there...and then bring it back to the Mac and re-link it to the real footage to do the detail work.
I've had a lot of fun playing with iMovie on the iPad. I am drooling for something similar that works as part of a Final Cut Pro workflow.
Interesting news, but the bit about booting competitors is downright disgusting.
I'm a little confused...why was Avid presenting at a Final Cut Pro User Group's meeting anyway? Do they just come in and are like "Hey, you've all made a mistake!" or something?

Well being Best Friends has it's advantages. And his DM is actually pretty cool. The store that received 5 of them that he is getting the 2 from, they are all idiots in that store. The Manager is literally Cross-Eyed, Employees don't even greet you when you walk in and are not very knowledgable. It's a shame too because I use to work at that store for several years. Received many trophies for sales. Including this one...

What's really sad is that it's a Mall store. Use to be a Million Dollar plus store. Now it has dropped well below that. Although it was back in the day when they actually cared about their employees. They have such a high turn over rate anymore. I had quit because I got tired of the DM (Different DM then) threatening us with our jobs everyday during Golden Quarter. I left my keys on the desk and never returned along with a few others Managers at the time.
They stopped handing out awards and plaques to their employees and stores, but they are still happy to threaten your job.

We are still missing an 8" Galaxy Tab to complete the 7", 9", and 10" line of tablets.
7", 8.9", 10" :)
i'm looking forward to reviews of that 10" samsung galaxy tab. the hardware seems sleeker than the original design they previously introduced. i hope it still has dual stereo speakers on both sides. i'm guessing that they reduced down from 8mp to 3mp camera due to the price matching and not because it's thinner, since phones can easily fit 8mp cams in their slim forms. i also hope that they don't mess it up with that touchwiz interface, as far as updating the os. at this stage of honeycomb, you'd figure that google will be rolling quite a few updates to it. although, engadget reported that there will be versions that will come vanilla.

http://www.macrumors.com/images/macrumorsthreadlogo.gif (http://www.macrumors.com/2011/04/27/apple-officially-addresses-location-data-controversy/)
Apple officially acknowledged (http://www.apple.com/pr/library/2011/04/27location_qa.html) the growing controversy over the logging of location data on the iPhone and iPad. The document comes in a Q&A format. In it, Apple addresses some common concerns and explicitly states that they are not tracking the location of your iPhone, has never done so and has no plans to do so.
The go on to explain the reason for the logging of data:
Why is my iPhone logging my location?
The iPhone is not logging your location. Rather, it’s maintaining a database of Wi-Fi hotspots and cell towers around your current location, some of which may be located more than one hundred miles away from your iPhone, to help your iPhone rapidly and accurately calculate its location when requested. Calculating a phone’s location using just GPS satellite data can take up to several minutes. iPhone can reduce this time to just a few seconds by using Wi-Fi hotspot and cell tower data to quickly find GPS satellites, and even triangulate its location using just Wi-Fi hotspot and cell tower data when GPS is not available (such as indoors or in basements). These calculations are performed live on the iPhone using a crowd-sourced database of Wi-Fi hotspot and cell tower data that is generated by tens of millions of iPhones sending the geo-tagged locations of nearby Wi-Fi hotspots and cell towers in an anonymous and encrypted form to Apple.Apple states that all data that is transmitted to Apple is anonymous and encrypted and can not be tied to the identity of the user. They also note that findings that the database continues to grow despite Location services being off as a bug that will soon be addressed.
Apple is planning on releasing a free iOS update in the next few weeks that performs the following:
- reduces the size of the crowd-sourced Wi-Fi hotspot and cell tower database cached on the iPhone,
- ceases backing up this cache, and
- deletes this cache entirely when Location Services is turned off.
