Eriisa: They came out with a Release Candidate of Windows 7 earlier this month.  For that you need not be a member of TechNet or the MS Developers Network.

But as with the Beta, we're pretty much "on our own"--without official tech support from either Microsoft or (probably) your PC's manufacturer.  The RC is also designed to begin automatically shutting down your PC every couple of hours some time early next year (I think), unless and until you install a genuine version of the OS.

Since we don't know how much that will cost, I'm trying not to burn my bridges at this point.  I'm also not thrilled by the lack of Windows 7 drivers right now.  Sure, I like Windows 7 RC so far, but I'm prepared to roll back, if I encounter too many problems or don't like the eventual cost.  Right now have set up as dual boot with Windows 7 and Vista, but I'm keeping the option of uninstalling 7 RC, and reclaiming that HD partition.
