Microsoft has released beta 1 of Windows Vista. You can download it if you have an MSDN Subscription from http://msdn.microsoft.com/subscriptions/. It's a hefty 2.42 GB DVD ISO download. I am downloading it right now but I guess I have to clean up my machine to make some room to install it. Hopefully the beta will feature the new OS installer which should get Longhorn installed in 15-30 minutes.
