Despite all this wall of text the one thing voids everything: you haven't even tried the new OS. And thinking that "knowing a thing or two about UI" makes you better than Apple… well, I'll leave it here. "Apple is going downhill since Steve Jobs" and "this is a buggiest (i)OS( X) ever" got old years ago. Just look up comment after any major upgrade of OS X. It will be a deja-vu. People compare the last x.x.xx release with tons of bugfixes to the y.0.00 and are so shocked there are bugs. Well, duh.
