Wifi Zune sharing is just awful in my opinion. You share songs with other zunes, and they will only last 3 days or 3 plays. You cannot access internet with it, or anything like that. Its WiFi is only good for that Zune to Zune sharing. Also...
"Caution: Zune may suddenly accelerate to dangerous speeds. Zune Contains a liquid core, which, if exposed due to rupture, should not be touched, inhaled, or looked at. Do not use Zune on concrete. Discontinue use of Zune if any of the following occurs: Itching, Vertigo, Dizziness, Tingling in extremities, Loss of balance or coordination, Slurred speech, Temporary blindness, Profuse sweating, or Heart palpitations."
Personally I think ipods and other mp3 players are pretty durable at this point, of course as with any hard drive mp3 player dropping it will screw you over, that is not the players fault per-se. You still had to say "Zune software" is easier to use. How about mp3 players that don't require software at all?
I don't think the Zune is revolutionary nor do I think it is the new ipod, or better than other mp3 players.
