I have a mixed bag when it comes to the whole "modern pc" thing. I have Windows for playing games on and Mint for doing all my day to day work orientated stuff. I then carry an iPad for playing random crap on when I am on my break or want to brows somethign on the internet.
However I do use my 600 on a daily basis for playing games on. I am also learning AMOS and doing stuff with Backbone.
