Debian is about the best you can get and most other distros are based on it, but you do sometimes have to put your head under the hood, some latest hardware might not be found right of but you can get them 99% of the time running, and you will find answers on the Internet unlike windows where you will find just people with the same problems..
Ubuntu does work straight out of the box take a LTS version (10.4 now) and you can test it before installing it.
Its just like windows but is a real multi thread OS and works great
Also its good to be sure and check before buying hardware if it is nix compatible.
