, once you make the move to Linux you are going to be wondering "why didn't I do this 5 years ago"? It doesn't get much better than running a modern, fast, secure, stable OS on older hardware. Always brings a smile to my face.
But, I doubt that Microsoft will miss either of use...
Hey Neil, I used the Linux (Ubuntu 9.0) before in my old Pentium 3 computer, I liked it for a while but then when the Ubuntu 10.0 version was upgraded I found it slow and the graphics was not working well, the old Dell desktop computer was at fault though. I may try a dual boot and dual partition with Ubuntu and Windows Vista to keep my old T30 laptop running until it runs out of air to breath.
