Multitasking. The iphone has an app called "backgrounder" which keeps apps running in the background, but its nowhere near as fast or as cool as the n900. You dont have that multi task screen that shows all the open apps, but it does what it says, so technically, multitasking is possible on the iphone, just not nice as the n900 Faster I put that in bold because I think its very important and was one of the main reasons I switched. Im not talking about faster at browsing or faster in apps, im talking about speed in general. For example, the music player is very quick and I can scroll down the list without any lag. With the n900, it always skipped and got stuck going down a list of about 1500 songs. Also, searching songs on the N900 lagged and froze up sometimes. On the iphone it searches INSTANTLY, and there is absolutely no lag at all. Its not just the n900, most smartphones lag at this, I dont know how the iphone managed to be so quick. All of the native iphone apps are speedy and ive never had even a 2 second lag.
