I'm sure Windows 8 has plenty of good points... But it's hard for me to break out of my "skip-every-other-MS-OS" take on the Windows brand. I mean, my new laptop arrived last week and I went out of my way to make sure it was Windows 7 Pro with XP Mode support instead of Windows 8.
That may be not wholly rational, but it's my own consumer behavior. Plus, heck, I'm a PC, and Windows 8 doesn't look like a PC to me.
