Indeed. I am using three gmail accounts on the NotePro 12.2.
You get circles with the user photos on the lock screen and just click on it to change. Takes about 3 seconds to change, which is pretty good.
You get separate lock screens, desktop, etc. Seems good enough to have the tablet being shared between two persons, for instance. I'm not sure how safe it is if you root it and start snooping around the filesystem, probably not at all, but decent enough for most users.
