I have to spend a fair portion of my time developing in dotnet 1.1, and as I'm sure anyone in a similar position will appreciate, the more I get used dotnet 2.0 and above, the more annoying it is to go back to the early version.

It is a fine operating system, but after using Vista and Windows 7 at home, I find myself wanting to use them at work where I spend majority of my time on a computer. The problem lies in that Windows XP does the job, and there's 0 cost in moving forward as obviously its alre...
