Sadly though, I don't know how relevant it is due to Linux's desktop marketshare.

I don't think Mozilla had any chance in this market. Microsoft couldn't do it, Blackberry couldn't do it, Palm couldn't do it, Nokia... probably could have done it if they hadn't been sabotaged by Steven Elop, but still. After the iPhone came out, everyone else failed except Google, who I'd posit just got lucky with a couple of well-timed carrier deals in key parts of the world.

The only thing Mozilla needed to do was have more foresight than all of the other guys with far more resources... sure, I guess. I don't think the target you're giving them is reasonable.

The only gripe I have is that pre-installed software can not be easily uninstalled but I understand they need to eat there too so I'll give them a pass. Rearranging the icons took care of that particular irritation.
