As it happens, I have access to the Microsoft Solution Developers Network via the Academic Alliance. On a lark, I decided to check if I could get Windows 7 there. And surprise, surprise, I could! I would get it now, except for its 2.2GB download size. Since I won't leave the office PC running through the night, I'll wait till tomorrow.
But wait...isn't tomorrow also the release date for Karmic Koala.
Whatever should I get? Decisions, decisions. ;-)
