For those Windows users who simply must have everything, Windows 7 Ultimate offers all of the features from Enterprise edition but loses the volume licensing requirement. So you can think of Ultimate edition as Enterprise for consumers (and other retail customers). Windows 7 Ultimate is kind of a wild-card. It is available at retail and with new PCs, but Microsoft says that it will not be heavily marketed and will instead be "offer-based" via occasional promotions and offers from both PC makers and retailers. That said, the pricing isn't as bad as anticipated. I wouldn't be surprised to see Windows 7 Ultimate sell better than its predecessor.
