Windows 7 is available for download if you happen to be MSDN or TechNet subscriber. His friends Windows Server 2008 R2 and Hyper-V Server 2008 R2 will be also there in few days.
When Release Candidate went out, servers were under such load that even requesting a key was painfully slow. I hope that download servers will hold-on this time.
P.S. I will miss the betta fish.
