I would agree. If it were my decision, I would sell this through their iPod distribution network.
Assuming these stores want to carry it.
I'm sure BB will sell it since they already carry consumer Macs, and ATT will carry the 3G model. However, I'm guessing WM & Target will take a wait and see. They aren't going to want to risk space on an untested consumer device and, frankly, I'm sure Apple doesn't want to gamble on WM & Target employees trying to "sell" it, possibly damaging the brand.

maybe they will carry all the popular windows tablets instead.
