@conqueror-Go for Ubuntu Hardy because it 'just works'!Fedora 9 has some issues with Nvidia GPUs as they are no drivers for Nvidia cards at present.You can get 'nv' drivers but they wont run any 3D apps like games etc.Ubuntu is more user-friendly,has better community than any other GNU/Linux distribution and suits many GNU/Linux users.
Go to
www.ubuntuforums.org,type anything (any problem) in hte search box and i bet you will get a solution whereas other Distributions lack such support.IMO you should start off with hardy,customize it according to your needs.get some cool themes from
www.gnome-look.org and in no time you could make your ubuntu desktop look like this-

So,u cant say Ubuntu is bad at GUI.
Your bluetooth,pendrive,webcam(most probably),almost everything will work with Ubuntu Hardy.
Go Download it (32 bit version as 64 bit may cause some problems) and enjoy the power of GNU/Linux.
If you are a gamer,keep a dual boot with XP/Vista coz there ARE games for ubuntu but cant compete with those available on Windows
(Truth is bitter).
