Chalk another one up to those clever folks at Microsoft.
Want to take SQL Server 2005 out for a spin, but don't have a spare machine lying around to do it with?
Try SQL Server 2005 on a Virtual Lab running at Microsoft. They're using a web-based version of the Remote Desktop system. Depending on your Internet connection, its just like being there. I use remote desktop to administer my servers.
