Actually, I made the 'switch' back when Windows 8 RTMed a couple months ago. I put 'switch' in quotes because I've dabbled in Linux for several years already. But, after trying Windows 8 for just a couple of hours, I wiped my hard drive and turned my laptop officially into a full-time Ubuntu 12.04 machine. My desktop still has WIndows 7, I'm not leaving Windows completely. I actually really like Windows 7, and it's still necessary for work, Photoshop, Visual Studio, and some other programs that won't run on Linux. But, I'm also now diving deep into Linux, instead of just 'dabbling'.
