I like tinkering with Linux at times, and usually come back to SuSE. But the issue for me is that Linux doesn't really do anything that I can't do on Windows (that I need anyway), and it can't do a lot of the things that I do need, like running VS2005,
developing on .NET 2.0 and .NET 3.0 etc. For surfing the web and doing email its alright but I don't need another OS for that.
When I'm bored and want to play around with something thats when I usually start messing with Linux again.
