I'm running MDK 10 official on a Toshiba Tecra 8100 laptop at work. It's a PIII 550, and it works flawlessly (so far). I have 2 comps at home (SuSE 9.0 pro, and WinXP Pro on a P4, and a P3). Trying to dump Windoze, but wifey won't do it. I have gotten her to use Firefox though. It's a step in the right direction.
