Windows XP has been replaced by Ubuntu Linux as my choice of primary operating system. I have been using it for the last three months and the experience has been amazing. The startup/shutdown happens in an instant, the machine is more responsive and it’s a good feeling to know that you are using open source software.
I’m using Xubuntu 9.10 (a variant of Ubuntu for slower systems) since my 2.8 GHz Prescott- 256 MB machine is underpowered to run Ubuntu. You can surely expect a lot of Ubuntu-related articles in the coming months.
