I'll adopt Windows 8 ...
... when they pry BSD out of my cold, dead data center ... and Slackware off of my laptop.
I need a computer to work for me, not against me. I don't want KitchenSinkWare[tm] on all systems. Rather, I need minimalistic targeted systems that do exactly the job that I tell them to do, nothing more & nothing less.
More important, I don't do business with corporations which assume by default that I'm a criminal.
