I started using Linux after the Windows Vista Fiasco. I'll never switch back to Windows. Linux is compatible with my hardware, it's FREE and I get FREE upgrades too. I tried Windows 8 pre-beta and I have 3 things to say about it: LAME! GAY! and I WON'T BUY IT! If that's the future of Windows, then I'm sticking with Linux for sure!
I use it extensively, every day. It runs my phones, my tablet, my router, and powers nearly all the services I consume on the Internet, including everything at Goog and at least most of what we have here on Yahoo. The only thing not linux in fact is my Mac....that runs UNIX with some nice UI code on top.
