I was just talking about this with my roommate last week. I picked up a Nexus 7 when it launched and I leave it out for anyone to play around with when they're over, and my roommate uses it to check his facebook and stuff too. Our solution is that I use the native twitter, facebook, etc apps and he just logs in through chrome (it's a shitty solution really). I would love the option to login as myself and have basically just my account keychain applied to all installed apps. I can't imagine that would really be that hard for Apple or Google to do, and it would really take Tablets to a better spot in the market as they aren't really phones at all.
