I have Cyanogen 7.1 on my Nook Color with 2 Gmail accounts. I'd like to require a password to access them, but there seems to be no way to set that up. Only option to sign out is to delete the account. A tablet is a shared device in the coffee table - not in your pocket. I know gingerbread is a 'phonae os', but still, it's nuts to have no way to provide even basic privacy between accounts.
