Scott Hanselman came up with this site that tells you what version of .NET you’ve got and your shortest path to .NET 3.5.  I’ve tried it from a couple of different Windows machines (one virtual machine, one real) and it works pretty well.  When I browsed the site with my iPhone, it figured out I was running a Mac.

Especially useful is the JavaScript snippet he provides that lets you have that functionality on your own website.  I’ll definitely be passing this url around the office.
