Let me buy a damned non-OEM, non-third-party-warehoused Windows 7 (Pro) license for my mother, who is NOT comfortable and not likely to become comfortable with Windows 8. Killing Windows 7 license sales scant months before XP EOL is yet another clusterf-ck on MS's part. P.S. "The customer is always right."

If anyone has a valid, reliable source for these (I mean, for purchase -- I'm not asking for anything dodge-y), I'd appreciate a pointer.
