Windows 7 was released to the public last Thursday. I have been using this product since it was in Beta and never had it freeze up, crash, or otherwise misbehave. While no one should run out and purchase it, when you need a new PC, it is a great operating system. Microsoft has done a terrific job with this and hit the ball out of the park! Be sure to avoid upgrading from Vista as any upgrade has issues and leftovers from the previous version. Fresh install only if you must, but best to keep what you have and then when you need new computers, purchase them with Windows 7. You will be glad you did!
