I have been a frequent detractor of Windows Vista. However, after playing around with the Windows 7 beta for a while, I am very encouraged about this new OS. For a limited time, Microsoft is offering pre-order sales of Windows 7 home and pro upgrade packages (these require you to already have Windows on your computer). Prices are $49.99 and $99.99 respectively, which represent a 50% discount to the planned prices of these products at roll-out. I already bought 3 copies from Amazon (that is the limit, apparently, that Amazon is setting). Delivery is not until some time in October.
