my two cents. IF YOU OWN A JAILBROKEN IPHONE 3GS and install ProSwitcher the iphone is still very very fast as usual ProSwitcher is an app which runs very similar to the way the N900 multitasks. Even with heavy games and heavy apps running in the background the iphone still doesn’t lag. Proswitcher app is being promoted as not slowing down the phone. By the way the iphone only has 256mb of ram with no page file There is something nokia need to figure out to optimize the n900. The device is very very capable to run smooth but the UI needs a bit of work. Well at least the 4 desktops run well when panning. Give it time guys well get there. Well Hopefully :S
