I work for a tablet manufacturer, and I spoke to an Android product manager at I/O last year about this.

According to him, this is a feature that pops up once in awhile, but they have a long list of stuff to do and this is just one of those things that always gets bumped out.

From my perspective as a platform dev, I'd like to get into some of the technical problems with changing this, but I could end up breaking some NDAs or something. I'll just say, when you start mucking around with adding login code, file system changes, and the current dmcrypt encryption, you hit lots of fun design problems.

>you hit lots of fun design problems.

Single user login is a design problem! When I hand my tablet off to someone they have access to my gmail, gtalk, facebook, twitter, imap email, browser sessions and dropbox.

And that's just what I can recall on the fly.

Maybe the encryption doesn't matter? By default in Windows users are hidden from each other stuff but the files aren't encrypted so only the FS permissions are stopping them from reading each others home folders.

There are two your account and the hidden root account ;)

I think the concerns are the interactions between user accounts. I don't think anyone is too worried about the hidden root account having access to your user account data.

Hence the winky face.
