Buy from FM sounds great... I don't use my Zune to listen to the radio, but maybe I'll start for just that reason (I listen to my zune in the car, so I use it to hold all my music and have it plugged in via the aux input, and then I use the car's radio to listen to FM). Maybe I'll start bringing it in at night and use its radio while I code... I hear tons of songs on the radio (107.7 locally

) that I'd like to get, but usually I try to remember a unique bit of lyrics, search the web for that when I get home and then go grab it from the zune marketplace... you can imagine how often I bother doing all that.
Using the original Zune 30 myself, love that it still gets these features!
Hexic was a great game on the 360, I'd love to have it on the zune! Coolest feature for me though will be the ability to access the marketplace over wifi... it means I could browse and buy a song from my couch at home, without having to have my big 'desktop replacement' laptop on me...
