Microsoft will begin shipping Windows 7 on October 22.  But today through July 11 in the United States and Canada, you can pre-order the Windows 7 operating system for as little as $49.

Like Vista, Windows 7 will be available in several flavors.  Windows 7 Home Premium is the edition most Vista users will likely want to upgrade to, but Windows 7 Professional (which includes an XP virtual machine) may be a better upgrade for some business users. 

The Home Premium upgrade discounted price is $49, but increase to $119 after the pre-order sale ends. The Professional upgrade pre-order price is $99, but will cost $199 post-discount.

We’ve been using Windows 7 (the Beta and the Release Candidate) for a few months and are very impressed by how solid it is even in the testing phase.  If you’re a Vista user and don’t plan on buying a new PC in the next year or so, get in on this 50% off sale before it’s over!
