you honestly think an N900 cannot control a helicopter.

besides that, the N900 can charge or be charged by other smartphones,
it can quad boot (maemo + 3 other OS'es)
it can control a robot (as i said previously)
it can be used as a tv or xbox remote control.
it can jailbreak the PS3
its numerous keyboard shortcuts can do almost everything a PC does (screenshot, reload, open apps, zoom in/out... to name A FEW)
it supports mouse (and built-in virtual mouse) and usb sticks

comparing the iphone with the N900 proves you don't know what you're talking about.

it has the best multitasking ever created on a smartphone
a pretty good SAR value
dual speakers
camera lens cover
full flash web experience
its OS is fully customizeable
its qwerty makes it a great video game emulator

and so many more i'm tired to include now

sure it lacks apps and hype but it is light years smarter than an iphone

It's apples (literally) vs oranges my man.

even the N8 destroys the Iphone. check the "it's not technology, it's what you do with it" promo on youtube
