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 More apps. I know maemo 5 is new so it isnt a fair comparison, but the iphone just has so many apps, theres an app for everything. Anything you want, just name it and iphone will probably have an app for it. I guess its because it has the appstore along with cydia and installous, many different places to get your apps. Also, i was new with the terminal and command lines when I got the n900, and i learned a lot from there. I was happy to see that the iphone also has a terminal and the system files are very similar to the N900. I feel right at home.
