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.

Things don't just happen without money. People are increasingly adverse to paying for items like apps or news, or are only willing to pay so much, such that marketing needs to subsidise the product (e.g. pay TV, sport etc.).
There's no such thing as a free lunch.
Everything you see that is free is paid for by ads. Everything is made cheaper by them. Just ignore them.

1st point: It's factually inaccurate to make your first statement, as evidenced by your last statement. Kind of funny, don't you think?
In your second statement, you are comparing all Android software-running phones to a single model/product line, the iPhone. The iPhone (each generation) has out sold any single phone model (generation) over it's life than that of any offered by any other hardware manufacturer.
Your comparison is like saying Toyota has sold more cars than Ford has sold F-150s. That may be true, but the F-150 is still the number one selling truck in the US, even though it does not outsell the sum total of all other trucks by all other manufacturers.
You should compare a single phone model, say Motorola Droid or HTC Incredible. You are simply talking software. Apple is primarily a hardware company that happens to make the software for its hardware. (yes, I know about FCP and other software) They do not license the iOS software to other manufacturers, so comparison to Google's OS and number of DIFFERENT phones it runs on is really irrelevant to whether any hardware manufacturer has had a more successful phone than the iPhone.
VERY well said!

I thought they said that there was not any concerns?
There aren't any concerns, but since the media hyped this up so much, they had to address it. Now they have. Should be the end of the story. But it won't be since there are anti-Apple folks who will push to keep this story alive as long as they can until the next Apple-gate story gets created.

He could have released this years ago.
Why should he? He released the short form BC, which is valid and legal proof of citizenship.
Hawaii law states that no one can request an original long form BC, not even the person who's name is on the BC, so Obama had to call in a few favors to get this. I'm surprised the right wing loons aren't accusing him of overstepping his bounds and destroying states' rights to get it.

If one were to buy a mac pro now, is the processor upgradeable to Clovertown in the future, or is that not really worth it even if it is, because you would need a faster FSB, meaning a new logic board, to take advantage of its power?
i think it is socket 775 or what ever. and if clovertown is pin compatable it will work. i think the processor will have to deal with the slower bus. as long as it is pin compatible.

They have become the Microsoft of the graphics world. See what having lots of money can do to you? Makes you cocky. That's one big reason I don't want Apple to gain much more market share. I want them to have just enough to keep them working hard... not so much to make them fat and lazy and greedy.
Wow, interesting.
I think Adobe is actually pretty good upgrading their software. As for Photoshop, Illustrator and After Effects they seem to do major upgrades every 18 months. I think is very reasonable. Plus is a normal thing when you are on the top to slow down a little, and frankly I don't think they are doing that.
CS3 will be here next year alongside possibly with After Effects, so what's your problem with Adobe?
As for Microsoft, I agreed that they are very slow when it comes to Office suite for Mac.

My 3GS (bought launch day '09) is starting to show it's age -- I'm seeing more "Searching..." and "No Service" when using 3G, and it's been forcing me to dump back to Edge on a more regular basis. Additionally, the battery is really not where it was when I first bought the phone.
I'm eligible to upgrade, but I don't want to lose all my app investment by going over to Android (plus, I'm just not a Google fan -- seems like they're trying to control everything on the internet these days) and I'm certainly not going to buy a phone made of glass that's almost a year old.
Apple needs to hurry up and make the 5 happen.

The hypocrisy coming from the left in the media on this issue is palpable... all the talk about Obama's great coalition and how its a justifiable war. Here are a few of my favorite quotes from Brhawk Obama:
�I�m gonna read this and then tell you who said it. �The president does not have power under the Constitution to unilaterally authorize a military attack in a situation that does not involve stopping an actual or imminent threat to the nation.� Now that was Barack Obama who said that on December the 20, 2007. We�ve got to be very sure here that we follow the Constitution, and president Obama didn�t do that.�
�Well, look, if that�s the criteria by which we are making decisions on the deployment of U.S. forces, then by that argument you would have 300,000 troops in the Congo right now � where millions have been slaughtered as a consequence of ethnic strife � which we haven�t done,�
Oh yeah... and here's a fun little nugget for those who like to tout Obama's coalition:

Ridiculous. Mac OS X and iOS can never merge because their UI paradigms are completely different. Why don't people understand this?
And on what computers would iOS apps be developed on of Apple were to can the Mac? iOS may be much more popular, but the Mac is more popular now than it ever has been and still makes then plenty of money.
You're too lost in a programing manual to see the point people are making. Blending is taking 2 things and mixing them together, or parts of things. Merging would be taking 2 things to make 1 new thing. Don't be so literal.
A more unified experience is definitley in Apple's plans for the future of both OS-es. Not my opinion. They've said so. That does not say, however, having one OS to rule them all. Lion takes a lot of cues from IOS (have you looked at it? Watched the Back To The Mac keynote and listened to Steve Jobs talk about this strategy?) The Mac OS will get more IOS like over time. And that might not be a bad thing. Jobs claims they don't want a touch screen Macintosh, yet they've patented the hell out of them and have bought components and things (obviously they've got something in the labs). When that day does come, and it most likely will be sooner than later... a blending of the two OS-es makes a lot of sense. The way people want to interact with technology is changing. Your operating system has to change too. To something more exciting that what we've had since the 1980's. Apple holds a patent on a sensor that works something like the Kinect does. This is where things are going. In a few years you'll swipe i the air without the need to a track pad. A mix of touch, sight, and gestures and perhaps voice. All this tech is here and has been for awhile. Time for the software to hit puberty, and this is the right track to go.
Personally, I'm bored with IOS and Mac OSX on an aesthetic level. I don't want the ugly IOS folders for my Apps anywhere, but I don't want the same old finder either.

Ignoring all else what I want is the ability to run my IOS applications on Mac OS. :)
You may get your wish soon. It appears that Lion will be Step 1 in the blending of the two OS's. A bridge. Step 2 may very well be the one & only Apple OS - based on iOS.
There's too much money in the volume sales of iPhones & iPads for Apple to focus on anything else. Other than the lip service they give their long standing computer users, the current obsession at Apple is sheer profits & volume sales of phones & pads for bragging rights and the money that goes with it.
The handwriting's been on the wall for years, ever since the company was renamed, and that fact has been underlined by the official words of Steve Jobs when he said "Post PC ERA". He was not talking about a few years from now, but mere months for Apple.
This represents the zenith of Jobs efforts. Perhaps the last item on his bucket list. To morph Apple into a huge, successful consumer electronics & entertainment business, is the goal & it's nearly complete. It wouldn't surprise me if the book is too.

What's funny is that even if new MacBooks and MacBook Pros were released tomorrow with the newer Merom chip, 90% of you folks in here wouldn't notice a difference in your daily computing. You would not say "OMG, this 64 bit processing and extra .16Ghz speed is AWESOME!!! I can't BELIEVE I lived without this for so long!!!" You wouldn't even notice unless someone told you.
Sorry but I've heard this so many times it gets pretty annoying. Dont assume to know what ppl want to use their Macbooks for. I want to use it for music production which can be very intensive on the processor, other people for graphics etc where a few seconds shaved off processing times when added up many times can make quite a difference to productivity.
Also, when the new chips come out it will instantly knock a chunk off the resell value - yes this is always the way with technology but buying when an update is coming soon seems silly.
