If you are comparing Unity to Mac OS X then of course you are going to be disappointed. IMHO and in those of many others, OS X has one of the most polished UIs out there, thanks in part to the fact that it is more than a decade old. Unity is relatively young by all standards. 1) I don't really understand what is the problem here. Could you be more explicit? Perhaps this is not your gripe, but since the switcher threw me off at first, this is what I have learned: if you want to switch b/ windows of the same application Alt-` will do the trick, same as in a Mac. If you press Alt-Tab and leave focus over an application with multiple windows the view will expand and show thumbnails of each one, if you can't wait you can switch from Tab to ` without releasing Alt and it will do the same thing. 2) I have never incorrectly pressed the Alt key, but alas, this is just me. 3) System Settings panel, to get there press the Win key(or equivalent) and start typing "settings", it should come up as the first result. You might perhaps find the different setting panels lacking in options sometimes, but a quick google search and a short trip to the command line has always worked for me. 4) I am assuming you mean to say that you have a launcher icon on the dock for a certain application and when you click it it spawns a new icon. This has happened to me mostly with applications that invoke a bash script to start (Matlab in my case). It is more of a problem of integration of external software with the Unity interface. This is to be expected for a relatively young platform. 5) See 1. 6) I don't know about Chromium but Google maintains their own repository so getting Chrome and keeping it updated is relatively simple. Perhaps there is a similar solution for Chromium? The Amazon thing really pissed me of at first, but uninstalling it was as simple as executing "sudo apt-get remove unity-lens-shopping". There is also a setting in the Privacy settings panel that I think that does the same. Also 12.04 doesn't seem to include the Amazon lens. I understand not liking Unity but there is no need to go in a self-described nerdrage rant. You could have found the answers to all of your questions with a quick google search, just like I did.
