Not quite multitasking
Multitasking has as much to do with the GUI for switching as what happens when you switch. What the video demonstrates (my thanks to the person who posted it), is application switching. The apps appear to quit and save state then reopen when invoked as before. You're simply not returning to the full homescreen to open another app in between. I suppose if the state saving and reopening was infinitely fast it wouldn't matter, but that accomplishment would have necessitated a press conference in itself.
If the apps you plan to switch between can't or don't make use of one of those 7 supposed multitasking APIs, all Apple has provided is a new task switcher.
If you want real multitasking, well, actually, I won't bang the jailbreaking drum anymore than my signature already does...

Yeah, the iPhone doesn't suck.
I'm far more interested in usability than a check list of features that are there but poorly implemented.
Hiya! I'm new to the iPhone dev subscription package. If I'm active can I download the 4.0 os to my phone? Thanks!
Please can you find a phone from a decade ago that had a camera, let alone a flash and you can be removed from my plebe list.
who cares. the flashes in camera phones suck. i've never seen one that actually helped the picture.
New Calculator Icon
Not that it really matters, but I noticed in the iPhone OS 4.0 Polish video that there is a new Calculator icon.

I would suggest you look at the Xeon Flash that some Nokia phones(and I think a Samsung phone or two) use to offer.
completely agree with this. my 3.2 megapixel camera with flash on my BB has never taken a good picture. all the iphone pics i have seen come out 10x better! please dont say itll help night time pics either, i dont even know why people bother trying to take pics at night with ANY phone, it just wont look good.
Very cool. Soon we will have the option of a variety of several physical devices from a nanoiPod to iPod/iPhone to iPad to iMac. Each could be connected to an external display, wired or wireless keyboard, mouse (yes, mouse), hard drives, etc. The whole thing becomes a system that is integrated across multiple devices sharing processing power. You have the option of a central computer, say an iMac, in your business or home and all the other devices become independent windows to its processing power and sharing backup data.
Uhhh... I can't think of a single reason why Apple's implementation of multitasking won't work perfectly for 99.9% of people. It does background music, GPS, etc. I mean, I am not trying to render a 3D model on my device here. Plus, app switching will be incredibly fast on a 3GS, iPad, and new devices.
I just don't understand your complaint AT ALL. The "true multitasking" arguments that many people have just don't use any consumer-based logic. They are 100% geek and technical arguments that don't matter to real-world people.

The journalist misunderstood the multicore concept...
It is true that Grand Central Dispatch can leverage multiple CPU cores, but the PRIMARY use of it is to leverage the much more plentiful *GPU cores*, which are already present on both the iPhone and the iPad.
Just as an example, I have the lowest end GPU supported by GCD in my MBP - an 8600GT. But it's 32 wimpy cores have twice the net GCD performance of the 16 SIMD lanes on my Core2Duo.
That's what's so wonderful about these new technologies - they make SIMD multicore programming and GPU programming hte same.

You were warned in the news. Mute your Computer with one button press. No big deal.
So doesn't that video show that you close apps from the list of running apps by clicking the little minus sign?
Doesn't that conflict with the Q&A?
"Q: How do you close apps when multitasking? A: You don't have to. Jobs says that if you see task manager, you blew it. Users shouldn't have to think about it."

i don't even use the built-in flash on my dslr.
i like the os changes. i hope it comes to verizon, but doubt it.
Maybe "you don't have to" close the Apps, but you can. What sucks about closing the Apps is that you have to hold each one. At least allow us to close them all quickly if we wanted to.
Empty space is beautiful. Typographers and designers call it "whitespace", where there is nothing. There needs to be a balance. It's very Zen-like.
This is the problem with a lot of websites. Everything crammed together. Nowhere to rest the eyes.
It does... So Jobs thinks they themselves blew it. Back track on this Jobs...
EDIT: Regardless off the "quit" feature, what Jobs said makes no sense. Wanted or not, the thinggy that replaces the normal dock is task manager.

Yep, it already has real apps, by real developers that users actually want to buy and use. When the HTC gets that, come back and troll some more.
