Today the European pre-orders started for Windows 7.

Amazon currently have Home Premium E for £44.97, and Professional E for £89.97. That's less than half of the normal price.

(Disclaimer these links go through my Associates account).

Keep in mind these are full versions not upgrades. So it really is a good deal, the only disadvantage is you cannot perform upgrades at all with these, due to Internet Explorer being removed from the European editions. You also get both 32-bit and 64-bit versions in these packages.

Get 'em now while they're still for the offer price.
