BTW If my Nexus7 shuts down randomly, I wouldn't be as Mad compared my phone shutting down randomly in the middle of phone call or in random place while using Navigation.
I've never had my phone restart at a particularly bad time. I guess I'd feel different if it rebooted mid-conversation or something (I seem to recall my Motorola RAZR doing that to me once, but it was just one thing).
My Nexus 7 issues are of course merely anecdotal, but I did blog about my solution and that blog entry got a lot of hits and responses (and my blog usually gets few hits or responses).
