Two years ago: company exec (Mac fan) buys a Surface Pro to show off our .NET application to customers as he travels. Hands it to me (I build releases) and I iron out a few Win 8 bugs since we'd always used Win 7 before. Get it set up, get to like the device a little, he takes it home... and returns it within 24 hours because he didn't mesh well with Windows. (Again, Mac user.)

8 months later he buys a Surface Pro again. I install our latest release, verify that everything is working as expected with hardware we normally don't use, and give him a controlled setup that will just work when he's at a customer site. Once again, he returns the Surface within 24 hours because he can't get used to Windows.

At least we verified Windows 8 compatibility, I guess.
