I decided to move my laptop from Windows to Ubuntu (Dapper Drake) after 3 weeks using dual-boot (Windows - Ubuntu). I only have a little experience as a Linux user but Ubuntu gave me an attractive impression. It supports me basic features I need also it's easier to use than SuSE and Fedora. Another thing, it's really fast and only need 1 CD to install.
After my Samsung Sens X10 is fixed, I will install Ubuntu in my Dell Inspiron 8600.
And beyond this, I decided to move a big bigger thing... ;-)
