Minus the Ads (Score 1)

I'd use it, but it wouldn't be long before me or someone else would find a way around the adverts and hence have a free OS. A friend had a free internet connection a few years ago which was advert powered, I simply made a program to hide the ad window, and we had a free connection. If this caught on MS would pull the product. URL blocking would not be enough, they'd simply include the ads in the windows update or something.
