Its Ubuntu 8.04... Its amazing! really the only reason i would sudgest linux mint over it for n00bs, is cause its a bit more ready to use right once you get it insalled.. However Ubuntu is better overall IMHO. but it doesnt come looking like that.
It looks like this
but thats the magic of linux, is almost everything is customizable.
and about drivers like wireless and sound... most of the time its very easy to get working. for me i just had to install it on my laptop then download the updates, then everything worked perfect... for my desktop i just had to turn it on and download the program envy ng and click install nVidia Driver. and everything works perfect on both of them.
