Well if we're sharing experiences, after all my yap, chat, and craptalk, I'm staying with Ubuntu. Why? Because Clonezilla norked up my openSUSE image that's why! Restored it yesterday, and it seemed to have done it OK, but it buggered up GRUB irreparably. Usually you can fix GRUB quite easily, and openSUSE still uses GRUB1 rather than 2, so I thought I'd be able to sort it, but nope. I get GRUB Error 6, and nothing I do can fix it. Tried restoring it with various commands, tried rescue discs, nothing.
So re-installed Ubuntu 11.10 fresh using a proper final image rather than my daily build one, and all has gone well. Dunno if it's just me but not had the problems this time with Google Earth and various graphics glitches, though I will add both Chrome and Earth are a massive PITA to install on Ubuntu 11.10 64 bit.
So it's about a month till the new openSUSE comes out, at which point I will re-assess Ubuntu and see how I feel. Again.
