Well, once again, I'm leaving Ubuntu, this time for good. I keep coming back because of the cool improvements that continue to be made to Unity. The Webapps, lenses, even the Amazon search feature are all pretty neat, and I do like Unity alot.
But what really ruins the user experience, is the fact that Ubuntu just isn't stable, reliable or quick; it's a pain to use. Last week I had a working 12.10 install, it ran very nicely. All of a sudden, the filesystem (Brtfs) randomly became corrupted. So I retrieved my files, and installed 12.04 with 3.7.5 kernel. But wireless reception was terrible, it hardly ever worked, and when it did, it would stop working randomly, resetting the wireless manager from command line wouldn't fix it, only a reboot would. So I tried to install 12.10 again, and all of a sudden it wouldn't install grub. I changed some settings thinking maybe I did something wrong, and again grub wouldn't install.
So, not having the time nor patience nor patience to fight with Ubuntu (and have my system randomly break weeks later), I installed openSUSE 12.2 Gnome. It installed perfectly, runs quick, and wireless reception is much better.
You'd think if Ubuntu were serious about marketshare, they could get it to work without constantly breaking and headaches? And my machine is pretty standard, it's new, but uses nothing but Intel components, all supported by the mainline kernel.
