I didn't have a problem with the installation. And I like the new desktop options/context. But as a person who said Windows 8 is ok for power users, I keep finding reasons that it is worse off than I thought.
But only a few reasons in the past week (when I got my new laptop) would be: unable to use tiles (fixed that), unable to connect to the internet ("fixed" that), unable to get the tiles to connect to xbox live (fixed that), and startup programs not starting up at initial login (workaround for that). I mention those things specifically because as a power user, I can (for the most part) figure those out. But as a normal user? Ha, good luck with that...
