Can't use Bluetooth to move files around...
This last one was especially interesting -- a few people told me that they now use their mobiles as storage devices for files -- word or powerpoint documents -- so that when they are at a meeting they can say "oh, let me transfer this white paper to your computer via bluetooth." Wow. I hadn't even thought of doing that with my mobile!
