MS if offering their express products for free!! you have one year to download them before you can no longer obtain the free versions. The version you download will be free for ever.. it does NOT expire after the one year term is up. The 1 year is just the window in which you have your chance to download it to obtain the free version.

There, now you have no excuse to NOT make the move to .NET :)

Cool. What are the limitations in the express version?
