TL;DR Ubuntu is moving wayyyy too fast.
If you think that the pace of technological change is too fast, or if you think that the music is too loud and those young hooligans should get off your lawn... then please stay on XP; but don't hold back the rest o us who will move forward without you. I look forward to your similar rant against Windows 8 with it's hand-held interface design.
The point that I disagree on is that Mark Shuttleworth & CO are releasing software every 6 months that in many cases (myself included) breaks comparability with hardware. This among other problems has IMO caused Ubuntu to fall to #2 on distrowatch, while Linux Mint which includes MATE and a much more customizable gnome 3 has risen to the top. If they can really make it against apple then more power to ‘em.
(yes I know Ubuntu does not include gnome 3 by default but both gnome 3 and unity depart from the traditional win95 style desktop)
