The coolest thing to do with BT 2.0 (which, I don't think the N80 has. It has more BT profiles than 1.2, but not enough to be considered 2.0, if I remember correctly) is to use a BT headset on a call, control your computer with Bemused, transfer files with right-click, and maintain a PC Suite connection all at the same time. My N70, N73, and E70 did this, but I'm fairly sure that I couldn't do all of that at once on the N80.
