MMS

Better Battery (not a biggie though. i have learned how to use the n900 to get the most out of the batt)

File transfer via instant messenger

scrolling in file manager or music library by using arrow keys

Video calling (low on the list though)

file sharing via bluetooth built into the ui like the rest of the sharing plug ins

Printing and word editing capability

calendar that's more intuitive and easy to use
