I'm OK with manual updates, I disabled autoupdates on Google Play too because I can't trust the apps to actually update them and not remove some functionality or worse.

You are right that the download / install process is very quirky. It often fails to provide the right feedback about what's going on and errors are common. Is it downloading, is it installing, did it get my touch? However I really want to install from there and not from Google.
