It's amazing we even have a Staples anywhere near where I live. I've never seen a Best Buy. They'll have some more before the special price ends in January.
@dentaku: Try Best Buy. They are definitely selling the OS and devices. And there is always the MS Stores - if there is one nearby, it is worth the trip.
If you can wait a week or so, you should see a new wave of x86/x64 touch devices hit the stores - the OEMs are releasing the rest of their models just before Thanksgiving.
