This is one of the things that actually bothers me about how open source the Android OS is. I must get a half dozen "program updates available" every week, which can be a pain to constantly install. And, when Google Maps updates, something noticeable ALWAYS changes (I know that's the point of the updates, but that's not what I mean). For instance, sometimes Maps will orient my map with my travel direction up and sometimes North up on the screen, and this changes from install to install. Other interface things have changed as well, but I can't think of anything in particular right now.
I love that developers can create some amazing software, I just wish there weren't so many minor changes requiring update installs.
