Phoenix said:The pre tackles this a different way since the whole environment is really a sophisticated browser/renderer architecture. What you will end up with is something that is like having Firefox with plugins as opposed to a bunch of distinct applications. I certainly appreciate what they've done with the Pre and its not quite as limited for certain applications as I thought it would be - but there are still quite a few things that it doesn't do quite so well.
it looks like there's a couple ways to jump between apps (or app alerts) quickly on the pre. there's the whole card thing, plus I think I saw a demo with another type of bar that allows you to interact with other apps and see alerts.
at this point, that's the main area the iPhone lags. it's not that it NEEDS multitasking, it's that it needs a more elegant way to handle system messages and alerts.
