Unfortunately not many multithreaded apps - yet. For a long time most of the multi-threaded apps were just a select few pro level things. 3D/Visualization software, CAD, database systems, etc.. Those of us who had multiprocessor systems bought them because we had a specific software in mind or group of software applications that could take advantage of multiple processors. As current CPU manufacturing processes started hitting a wall right around the 3GHz mark, chip makers started to transition to multiple CPU cores to boost power - makes sense. Software developers have been lazy for years, just riding the wave of ever-increasing MHz. Now the multi-core CPUs are here and the software is behind as many applications need to have serious re-writes done in order to take advantage of multiple processors. Intel tried to get a jump on this with their HT (Hyper Threading) implementation that essentially simulated dual-cores on a CPU by way of two virtual CPUs. Software developers didn't exactly jump on this and warm up to it. But I also don't think the software industry truly believed that CPUs would go multi-core on a mass scale so fast... Intel and AMD both said they would, don't know why the software industry doubted. Intel and AMD are uncommonly good about telling the truth about upcoming products. Both will be shipping quad-core CPU offerings by year's end.
What you're saying isn't entirely true and may give some people the wrong idea.
First, a multicore system is helpful when running multiple CPU-intensive single-threaded applications on a proper multitasking operating system. For example, right now I'm ripping CDs on iTunes. One processor gets used a lot and the other three are idle. I could be using this CPU power for another app.
The reality is that to take advantage of multiple cores, you had to take advantage of threads. Now, I was doing this in my programs with OS/2 back in 1992. I've been writing multithreaded apps my entire career. But writing a threaded application requires thought and work, so naturally many programmers are lazy and avoid threads. Plus it is harder to debug and synchronize a multithreaded application. Windows and Linux people have been doing this since the stone age, and Windows/Linux have had usable multiprocessor systems for more than a decade (it didn't start with Hyperthreading). I had a dual-processor 486 running NT 3.5 circa 1995. It's just been more of an optional "cool trick" to write threaded applications that the timid programmer avoids. Also it's worth noting that it's possible to go overboard with excessive threading and that leads to problems (context switching, thrashing, synchronization, etc).
Now, on the Mac side, OS 9 and below couldn't properly support SMP and it required a hacked version of the OS and a special version of the application. So the history of the Mac world has been, until recently with OSX, to avoid threading and multiprocessing unless specially called for and then at great pain to do so.
So it goes back to getting developers to write threaded applications. Now that we're getting to 4 and 8 core systems, it also presents a problem.
The classic reason to create a thread is to prevent the GUI from locking up while processing. Let's say I write a GUI program that has a calculation that takes 20 seconds. If I do it the lazy way, the GUI will lock up for 20 seconds because it can't process window messages during that time. If I write a thread, the calculation can take place there and leave the GUI thread able to process messages and keep the application alive, and then signal the other thread when it's done.
But now with more than 4 or 8 cores, the problem is how do you break up the work? 9 women can't have a baby in a month. So if your process is still serialized, you still have to wait with 1 processor doing all the work and the others sitting idle. For example, if you encode a video, it is a very serialized process. I hear some work has been done to simultaneously encode macroblocks in parallel, but getting 8 processors to chew on a single video is an interesting problem.

Apple won't put GPS in unless they can create a whole new 'Apple' interface for it.
I'm no GPS expert, but I'm not sure how they could do that with a simple candybar phone. It would need to be some sort of smartphone / pocketPC thing.
I don't think size is much of an issue with GPS. The Chocolate by LG is a candybar slider and it has GPS in it.

There will be no Xserve Pro until there is an Xserve Non-Pro. Many people would love to see an xserve mini (http://www.roughlydrafted.com/RD/Home/3FE506E2-FD6D-4FC6-BC9C-055F27279DF4.html), but at present there is no need to change the name.
I think iSteve said, when he introduced the MacBook Pro, that they weren't calling it the PowerBook becasue they wanted "mac" in the title (and obviously to take out Power). A new name with a new chip?

The 1.83 & 2.00GHz for iMacs (if they use merom) and MacBooks and the 2.16 and 2.33 for the 15 & 17 MBPs respectively. Its that simple.
That doesn't make sense, marketing wise. If they do anything to the MacBooks and iMacs they would at least bump their speeds. It doesn't matter f the 2GHz Merom chip is faster than the 2GHz Yonah chip, the consumers don't give a crap about the chip... they want to see "them GHz numbers" go up.

Wow. Be a little more open-minded! It's not as if Apple is taking away much with Lion. If you don't wanna use launchpad, it won't force you too. Grouping expose by apps is good for most things - it doesnt make sense for each Safari window to take up as much space as a separate program. Fullscreen is very useful for focusing on one task

I think it won't be released yet, but they've got it to a strong showable point. Underlying architecture probably relies on a few features tied to Lion (QT stuff and more?). Maybe we'd need to upgrade to Lion for it. Ready to go in June or whenever Lion actually hits.

I doubt Apple will ship a new version of FCP before they ship lion, there are simply no real video editor APIs in Snow Leopard that are capable of 64 bit, QT Kit is a joke.
HOWEVER, according to the developer page for Lion there will be a brand new A/V API in Lion that will be 64 bit and FCP will most likely be written in that.
I guess they could back port the entire API to Snow Leopard, but I wouldn't count on it.
There is little to no technical reason the new framework couldn't run on Snow Leopard as a private API embedded with the final cut release. If the framework you mean is AV Foundation then they don't need to backport it all. It's Not a "New" API it's been running on the iOS branch of OSX for a few years now. So Snow Leopard shouldn't be much of an issue, it's just a matter of tying it in to GCD and the other low level fun stuff SL brought online. It doesn't sound like there is anything in Lion that will mean it will work different at those low levels to stop it working.
Remember Apple owns both the OS and FCP. The low level video boffins at Apple seem to have been working all along to get the framework read for this release. The suggestion that in a company as small as Apple that a team developed the AV foundation without the FCP people knowing about it till the last minute is kind of ridiculous.

This is a smart move. It had to happen sooner or later.
John Gruber would eat Steve Job's ***** if he could. His opinion is extremely biased.
I don't disagree that it was a smart move, either. It WAS a bait and switch though. Most of us realized that making the OS open would result in a ton of forks with horrible UI and poor casual user experience- look at Linux on the desktop.
I think Google is doing the right thing to give Android a better product. However, that doesn't make it not hypocritical, or the exact opposite of everything they promised their clients (the manufacturers).
Google finally figured out that they need to exert control to keep the OS consistent and the user experience good. Problem is, doing that also means going against everything they spent the last three years preaching against.
Also, it's extremely important to note that the criticisms being leveled against Google is that they're showing favoritism and imposing addition restrictions on competitors such as Facebook, if you read the articles.

So, you're comparing a mature product (Tiger) to one that's still in beta and which by all accounts has plenty of outstanding issues before it's ever released (Vista)? Ok soon lets compare Leopard and Vista.
The fact of the matter is that Vista has to be functionally complete now (or else they are going to miss shipping dates by a large margin)... so the functionality you see is basically what you are going to get. Put aside the crashes, performance issues, bugs and you can get a good sense for how it will operate when it is released.
Really MS has taken the transparency and visual effect so far that they are distracting and degrade usability (thank fully you can adjust them to some extent)... they are doing just like Apple did in Mac OS X 10.0 (transparent window title bars when in background, overly transparent menus, etc.) but thankfully Apple has been refining it for the last few years for looks and usability.
Also the new user security mode is going to be a big nightmare for folks until 3rd party software catches up with it... currently in my average usage it is always bouncing to out the full screen overlay with security confirmation dialog... I am at the point I don't read them any more since the disrupt what I am trying to do. (We have several developers in house struggling to keep up with changes and bugs in the beta, making it hard to get ready for Vista).
In the end Vista will be a good OS but it is going to be a little painful for the Windows world for the next year or so (into 2008).

I always wonder what people are thinking...
"Apple <or insert any evil corporation or government entity> has 100s millions of customers, but I bet they've singled me out for tracking with the black helicopters and vans because I make $25,000 a year and have access to the a state of the art Camry and have 2.5 kids."
or
"Those bastards at Apple <or insert again> are trying to figure out what I like to buy with their Genius tracking the songs I download, ads I click on, etc. to try to target ads and future products at me! Those sons of bitches!"
People, 1984 was long ago. You have no privacy unless you don't live in society, e.g unabomber. Get over yourself, you are not so special Apple is paying any specific attention to you. They want to know how many 1000s of people are at your Starbucks, but not you. Otherwise, encrypt your backups, chain your iPhone, iPad, Macs and PCs to your wrist, and shoot at anyone that looks over your shoulder.
Besides, the iPhone Software License Agreement is pretty solid on this front. The only hole to fill is why it might still be logging when Location Services is disabled. But at end of the day, this is a tiny tiny aspect of a much much larger issue - we use technology that will track what we do, influence us, etc. We have to learn to accept this. It's going to be impossible to stop this. Get over it.

One thing's for sure, Intel appears to have learnt a great deal from the Netburst fiasco -- how not to do things, if nothing else. Unfortunately, they still estimate ~50% of processors shipping in 1Q2007 will be netburst-based (mostly Pentium-D).
It is a shame, but sadly those are the real cheap chips right now. The good news is that they'll change those over soon enough with more Allendales, then millville and so on and so on taking on more segments of the market.
I think as they transition to 45nm we'll see more and more Core chips, simply because they'll want as much manufacturing to be on the new process as possible, and they don't need to scale the D's etc. down to it.

In US, people get free shipping for their new batteries.
In Hong Kong, we have to visit the service providers in person TWICE! First we have to go there and give up our old battery for registration. Then we have to wait for at least 10 days and visit the service providers AGAIN to get the new battery.
It's simply poor service from Apple!
P.S. The Apple HK support staff actually told me they just know about the news on the same day as me. They also incorrectly told me that only MacBook's batteries replacements have free shippings...

I'm real excited for the new iChat and Spaces, along with these new "top secret features..." They better be good!
The finder is definately my bet for something to be revamped, along with probably iLife which will be revamped for leopard.
Edit : Also something more with virtualization (boot camp area) as they did not touch that really.
My bets are on some kind of Boot Camp-ish feature that will allow for native installation of Windows applications -- without Windows -- right into OS X. It would obliterate the need for applications to be written for both Windows and Mac.
<ducks and waits for flamers to whine about how impossible this is>

I have two questions.
Do you think that one of the top secret features they didn't show was a unified interface? Because the UIs they showed looked just as hodge-podged as Tiger, ie iCal and Finder still brushed metal and Mail is still plastic. They talk about Microsoft copying Aqua, but I can't think of one app that is aqua anymore! What does Aqua look like?
Second, did the developers get a beta of Leopard? If so, won't we be hearing about whatever top secret features they didn't show? Surely one of the 4200 is a snitch!
