Hahah, what a stupid, misinformed article. Windows 8.1 (aka. Windows Blue) isn't going to be doing a "U-Turn", they are going to be improving what they already have and adding some new features based on feedback. Par for the course for point releases.
I've never have good luck with Ubuntu. It's always been pretty slow and poor response time. But as long as I don't leave the terminal or Gedit it's not bad.
Multi-monitor support is something I REALLY REALLY wish was better. And multi-video card support too. Windows 7 is terrible at running multiple video cards =\
