Improved phone functionality (as per N95 / N97) including

Full Nokia Car Kit Support with voice activated commands
Customisable ringtones per contact
Customisable ringtones per group
Nokia Media Player Aspect Ratio adjustment (N97)
Media Player built in Podcast support (so that podcasts do not show up in All Songs list, but are kept in seperate group)

I appreciate this device is much more than a phone but having these really useful phone functions taken off you hurts

Ability to group connections and assign groups to apps rather than individual connections (N97)

ooh and can someone port the Nokia Step Counter over to the N900 please. I love this app
