First Look: iOS4 on iPhone 3G vs 3GS
Multitasking Question
"With iOS4 on the iPhone 3GS and iPhone 4, double-tapping the home button brings up a list of open apps that users can jump to quickly. This simply isn't present on the iPhone 3G. The multitasking is probably more accurately described as faster switching between application. Only certain applications can truly run in the background, and the app switching doesn't necessarily show you other open apps so much as it lets you jump to recently used apps faster."
So only certain applications work in the background? How can this even be called multitasking?

What applications do you want running in the background?
They have it set up so that developers can allow only the parts of their applications that they need to run in the background of the phone run to preserve battery life and keep the phone quick. There are a LOT of applications that have absolutely no need to run in the background and the ones that do need background capabilities are absolutely able to be run.
It's more like "smart multi-tasking." because honestly, do you want to keep your fart app running constantly in the background draining the life of your phone and slowing it down??
Other things like "fast app switching" is just that, it allows you to switch from application to application without having to hit the home ...

i see it coming as an update for most apps.
I would imagine that since the applications currently out there were written before iOS4, then the code to run it in the background might not be there.
We shall see....

Only certain tasks are allowed to be performed by an application when it is not 'open.' Everything else is instantly cached.
It's not multitasking like on a desktop, since you can't have two apps on screen at once. But in the mobile realm 'multitasking' is a mix of instant caching.
Engadget has a good video of this working. It's honestly not really that much different than on the Palm Pre or on an Android handset.

Actually, you're wrong. Multitasking on the iphone is not just like Android. IOS4 will only allow certain categories of apps to run in the background, and forces everything else to cache. Also, the apps have to be coded to work with multitasking or it won't work at all. Android, on the other hand will allow processes to continue running simultaneously as long as there is available memory, and only stops the process and caches it when it is necessary to free up memory. Also, Android can restart the process later when memory frees up, without you having to ask it to. Android has true multitasking all the time and only resorts to caching the state of an app when necessary to preserve performance. IOS4, on the other hand, allows only limited app...

"it is far from being the same thing that happens with Android.",...
Good.
I don't want my iPhone to run like my Android phone, I mean, dear God! My Droid force closes at the drop of a hat, and who needs your damn "funny soundboard" application to be running in the background while you are playing a video game?
I honestly think Apple would be well off calling their version of multi-tasking "Smart-Multitasking" because it prioritizes everything in a very simple and elegant way while reducing strain on the battery and processor.
Engadget is reporting 38 HOURS of battery life under moderate to heavy use on their test iPhone 4... let me repeat that:

Umm... you can close applications that you don't want to run in Android. You don't have to have the OS decide for you what apps you want open and which ones you don't. The fact that you don't do that is probably why so many of the apps you do want tend to force close. Also, with Android there are different tiers an app can fall into which help the OS to decide how to manage your running apps when you decide not to. So not only are you in control, but Android will also do "Smart-Multitasking" for you. With IOS4 you don't have that versatility. But, that's always the way with Apple users. Less is more. I'm certain you think the EVO's larger screen is a disadvantage as well, preferring the smaller screen real estate on the iphone. And I'm sure ...
