Once a year or so I get all desperate for change and install linux, I end up trying to use WINE with everything because I dunno how to do stuff, and within a week it breaks. Last time I broke it installing steam with WINE. Also I have an ATI card and they aren't supported very well, if I had an Nvidia I'd give it another shot. The sudo thing is pretty awesome though I won't lie, it's fun just trying to type in random apps you want and see if they work, some of the times it surprises you and gets it. I think one time I typed in like sudo get-apt openttd and it installed it.
