Who knows which other walk-in stores in the USA do carry Nokia Internet Tablets ?

I plan on traveling to the USA next year January or February and was planning on purchasing an N810 at some CompUSA; now I am looking for alternatives. Internet order purchase is not really an option because a)my credit card is from overseas, b) Usually online stores do not like shipping to a hotel, c) I'd really like to feel the device before purchasing....(pretty sure I will fall for it anyway, but I'd like to see it first, then buy).

Thanks for your comments.
