Get it, while it’s hot!
A fun sidenote, though:
The RC will expire on June 1, 2010. Starting on March 1, 2010, your PC will begin shutting down every two hours. Windows will notify you two weeks before the bi-hourly shutdowns start. To avoid interruption, you’ll need to install a non-expired version of Windows before March 1, 2010. You’ll also need to install the programs and data that you want to use.
What a way to let users know they should update/upgrade! ;-)
