Is it a Galaxy Nexus? Because if not, you're talking about a pretty old device, and I hear people complain about their two+ year old iPhones all the time.
My own anecdotal Nexus experience (I own the Google updated GSM version): no crashes (although there was a brief syncing outage last night), updates are smooth and fast, and the whole "it just works" thing applies.
8 hours? What?
It probably goes without saying that iOS isn't for him.
But you're right about the error messages, when thing go wrong there are very few apps that will tell you about it.
I don't see a problem with just jumping back to the homescreen, most people will reopen the app right away anyway.
There's a lot of work to do in that field, and that's catching-up work more than improvements. It's much like discussing the Nexus One. Let's talk about it again in a year or two.
