Isn't the iTouch only up to 64gig?
Speaking of iTouch mine will not synch anymore, W7 will not reconize it. I followed all trouble shooting steps and went to the online forum. Time to make an appointment with the iPeople at the mall.
Not sure what the iTouch is but the iPod Touch only goes to 64GB as well.

As far as storage goes, anyone who can't decide on 64/80GB to put on a bike needs help. That's an insane amount of music and should be plenty!
