or just use one of theses for extra battery life
Amazon.com: MusicPower Encore Dual Port USB AC...
i bought one couple weeks ago and so far its been great!!
tho i dont use it much because i couldint run my zune or ipod nano 4gb down yet lol
but last night when i was playing Zune Pong by Steven Gilligan which is a very nice pong game by the way
it finely drained my battery to were it says your battery low tho it didint go dead and i problee used it all lastnight like 6hour to 7hours listening to music and playing a game with music for a hour or 3
im gona take the encore with me tonight sense its gona be a long work night and see how long it will keep the zune runing
it says on the box 15hours extra on ipod and mp3 players so we will see.
but ya rpgs and even rts will be very cool on the zune
