Could be. Currently mine is running XP. I've tried CrunchBang Statler on it with an 8GB CF drive and it was OK. I tried to run Osmos on it and it was an exercise in patience. Mines played OK on it though. Under XP I have VB.NET and C#.NET 2010 Express installed. They work, but are understandably a little slow. If your are learning the language the speed isn't too important.

I did replace the CPU fan with a SilentX fan. It's much quieter now, but runs slightly hotter.
