This may not be the best group to post this in, but .....

Windows 7 comes out 10/22. Probably not news to anyone.

From now until July 11th, a few places are participating in a Microsoft
"pre-order" program where you can buy a copy at a VERY steep discount
(50% to 70% off; $49 for the $119 Home Premium Upgrade, for example).
Ships on 10/22.

So I went to www.BestBuy.com/Windows7preorder to place an order, and
there are two SKU's ... Home Premium and Business.

Shouldn't there be four SKUs?

-Home Premium 32-bit
-Home Premium 64-bit
-Business 32-bit
-Business 64-bit

???

[Or does each package possibly include both, but you can use one or the
other?]
