I would try and sync your N900 with your computer. No phone can compare to the N900 when it comes to syncing to a pc. No, i'm being serious.

Also, I would start playing a podcast or video and then close the media player and reopen it. Just to show them how the N900 remembers playback position in the media player.

Those are just some of the basic things that the N900 can't do properly out of the box.

Don't talk about pwning someone until your phone can do the basics.
