My laptop is my only Windows machine . I run linux on my workstations for more than 5 years now. I think its a better more stable solution than windows. You should have some knowledge about linux to get full advantage of the power of the OS . Like kernel tweaking, upgrading and installing drivers, hardrive tuning etc. If you dont do that, linux can be very slow and instable.
Other than that ... Linux rocks as a workstation and server. Remotethumbs runs on linux
