Exactly.

Maybe this makes sense on Chrome OS. But for other main stream OSes like Windows, User accounts should be best left on OS. maybe a quick way to change profiles but that should be limit. Any further than this would be just reinventing the wheel & duplicating the features(parental control for example) that are already present in Modern Operating System.

on a related note, has anyone noticed memory usage of Google Chrome? Its crazy bonkers?

It makes sense on Windows and OS X too. I have a couple sites where I have multiple accounts, and it's nice to just fire up another instance of Chrome where different credentials are saved. Different extensions per account and so on. I shouldn't have to switch users at the OS level (which is slow) just to manage multiple online identities for me.
