Well I use Ubuntu (Ultimate Edition) for the last six years for the most part exclusively. I do have XP dual booted on 1 of my PCs for flashing roms its just easier, but thats it. I tried dual booting six years ago and over wrote my boot sector, didnt have an xp disc so I installed Ubuntu and never looked back. It is not the linux of old in fact I find advantages over windows simply starting with not being worried about viruses. Stability is incredible on better supported distros such as Ubuntu, Linux Mint or if you like a challenge the very beautiful Sabayon linux. One of the best perks is being able to use Compiz Fusion who most will claim is eye candy, once installed the amount of user possibilty is endless from one click entire theme customization to working on 4 desktops through the use of the 3d destop that is unsurpassed by anything windows has ever put out. I have to laugh every time my wife says how cool the windows shake animation is on her laptop running windows7, that is elementary at best. When I show friends my desktop, I usually have four or five guys asking me to come over and set them up. Having ANY knowledge of linux puts you in a good spot for a smooth transition. I will never turn back at this point.
