Just a couple of things... Backgrounder is not multitasking. It pauses the application and saves their state and you can easily switch back to them without restarting the application. I don't think it can really multitask properly. As you have one, can you let us know if you can still receive Skype/MSN/Yahoo IMs while you are reading a website or looking through your photos or music? A great demo of the N900's multitasking capability is to open a few windows, then open DrNokSnes and run a game. Switch back to multitasking screen (ctrl + delete or the camera button) and you can see the game still running in the window. The other point, the lag issue I think is due to the serial tasking nature of the iPhone. Even if all you do is open 1 application on the N900, the iPhone still has the advantage in that It doesn't have to constantly look for Skype/MSN/Yahoo etc IMs and so on. The iPhone can solely focus on the application you are using and little else. Of course, it is personal preference over whether you want multitasking or not. Not everyone wants IMs coming through or Twitter feeds etc while browsing a website or listening to music. The Apps are well known, but personally, I don't want to spend even more money after I've spent so much getting a phone.. the iPhone and the N900 do not come cheap
