Re: Good-bye Ubuntu, going back to Windows
Agreed, particularly since Windows 7 was a uniquely solid launch of a very solid OS. Unlike XP or 7, 8 has a lot to live up to. You're right that the reactions have felt a lot like the switch to Unity, a fair mix of legitimate criticisms and "it's not like it was last week! Change it back!"
Re: upgrading Windows, that's actually a thing now. I mean, previously, you could use a Windows 7 disk (set) to upgrade Windows XP and keep your files or whatever, but now with 8, iterative updates are released (free, reasonably) through the store UI. I helped a friend upgrade her Windows 8 install to 8.1, and there's an 8.2 on the way. It takes a long time, and there's a hilarious number of progress bars that don't tell you how many more progress bars there are going to be, and then the computer restarts about 37 times while throwing up progress screens with vague names that also don't tell you how many there are going to be, but it works. We giggled about sudo do-release-upgrade, but the machine also didn't hold up the entire process to ask her if she wanted to replace a config file in /etc, either.
I know I shouldn't use tildes for decoration, but they always make me feel at home~
