I don't think I'll ever like Unity
I remember spending an afternoon with a Win 7 beta tinkering with all the cool things the new taskbar allowed me to do, and consistently being surprised as I discovered more and more nifty features.
Having spent the same amount of time with Unity it's a case of running into more and more things I expect to work that simply don't or aren't there at all.
First thing was trying to move it to the bottom of my main monitor. I have 2 monitors with the right-most one being my primary, so by default Unity sits in the middle(!) of my screens. The solution? There isn't one, it's impossible to move it!
Now maybe I'm just silly for having my primary monitor on the right and should move it to the left. Oh, except I used to have it that way but Ubuntu's bizarro notifications system (you know, the one that 4 releases later still doesn't allow you to click on a notification) then popped up all it's messages half-way off the very top right corner of my second monitor, prompting the change.
I hope to see some improvements in Unity but given the recent lack of improvement to every other hastily introduced element in the last 2-3 iterations I doubt it. Official policy seems to be to introduce a badly thought through element in each new release, then abandon any work on improving it in favour of adding another new half-baked UI element.
