Adding BlueTooth capabilty to the iPod would be nice.
While like it has been stated here. It wouldn't be any good for the iPod's sound capapbility (the transfer rate is too slow), but it would be quite handy for the iPod's extra capabilities (contacts, memos, calendars, games, etc).
As for more iPod games. See this link <a href="http://forums.appleinsider.com/cgi-bin/ultimatebb.cgi?ubb=get_topic&f=8&t=000191
Strange, has anyone noticed that the iPod is becoming more and more like a PDA?
Personally, if the iPod would have BlueTooth capability in the future, I would like see an iPod to be used as a passkey. So that you can only access your computer provide that you have your iPod and your voice as the oassword (don't catch a cold!).
Just place the iPod near the computer's BlueTooth antenna, and said the secret password (which can consist of soem words, or a full phrase).
It would be quite handy in a place where you want your computer free from physical outside input intrusion (llike a fellow co-worker tapping on your keyboard to fool around with your computer).
