Things are changing and improving VERY fast in linux land lately, so being behind by that much is gonna pretty much set you up for disappointment, along all the usual reasons why you ideally want to be on the just dull enough part of the bleeding edge for linux desktop, where you are only getting a few small shallow cuts and hopefully no deep cuts...
Anyway, popular acclaim for popos reached it's peak just when those problems started to show up. It used to be better in years prior, but the reputation tends to lag the actual reality, so sentiment at that point was to recommend it even though it wasn't actually a good choice.
Honestly, give Linux another try four or so months from now. You will get to start fresh on a brand new Ubuntu LTS or the usual new Fedora release. Try Gnome or KDE, see which ones sticks the best with you. Just don't try anything else if you want maximum features, commodity and stability.
Yes, you were unlucky :(
