Yea, but if you want to use your mouse thumb-button to go back while browsing, you have to write 6 lines of code, rotate the cylinders and tune the cam-shaft...
I've tried Linux many, many times over the years. I give it a go and then get frustrated when I can't get things that should be simple to configure without having to jump through hoops. I really hope they succeed because I like competition. When I can double-click an executable file to install a program in Linux, then it'll be ready for prime-time.
