I take issue with your "One-handed opening leads to whole laptop lifting up instead of smoothly opening" item. I have this same problem with the MacBook Air I use at work. I can't open it one-handed, the whole thing just comes off the table. I can't think of any Ultrabook-class system I've ever not had this problem with and although it is a real problem you failed the mention that the MacBook Air is just as bad.
I'm also not a big Unity fan, I personally prefer Gnome 2.0, but even that isn't fantastic. It really seems like the new shells are all thrown together by programmers and graphic designers without thinking about usability. They're all designed to be pretty and have features. People just want a simple and fast way to get at what they want, not constant unneeded changes in interface.
