If you haven't made the jump to Visual Studio 2008 cause you don't have the bits, give a virtual PC a test drive. Microsoft is offering pre built virtual PC with several Visual Studio configurations. These are a perfect way to get a look at Visual Studio 2008 and not have to install it on your local machine. This can also be great for creating presentations.
Check out the full listing of Virtual PC Microsoft has made available pre installed with Visual Studio 2008 here: http://msdn2.microsoft.com/en-us/vstudio/aa700831.aspx These Virtual PC images will work until April 1, 2008, so that should give you plenty of time to play around.
