Has Apple mentioned where the device will be sold? Will this be sold everywhere the iPod Touch is sold? (Walmart, Target, Best Buy, etc,etc) or will it be locked down to mac dealers/ AT&T.
I personally think Walmart with their cellphone mini-stores are ideal.
Same goes with Bestbuy.
However I'm sure Target will figure out a way to sell it and a 3g plan.
It will probably initially only be sold in Apple stores or on Apple website. Just my guess though.
