Google This tweet from Tom Warren made me smile. So, it's 2012 and tablets are finally able to do what the Amiga did in 1985. Seems like a bit of a stretch to be excited about that, right? Sure, until I caught myself getting excited - only a bit, but still - by this piece of news. Update: removed me being an annoyed child.

"The Android platform takes advantage of the Linux user-based protection as a means of identifying and isolating application resources. The Android system assigns a unique user ID (UID) to each Android application and runs it as that user in a separate process. This approach is different from other operating systems (including the traditional Linux configuration), where multiple applications run with the same user permissions." (http://source.android.com/tech/security/)

So the Android architects decided to exploit Linux's multi-user support to enhance security in the system itself. I can't say I like the approach, but that's the way it is. It *will* be pretty hard to put multiuser support on top of that, I would say.

As for iOS, I'm not an expert, but paper published by Apple (http://images.apple.com/ipad/business/docs/iOS_Security_May12.pdf) suggests that UID and GID are unique for each device. I cannot say if they map to Unix/Darwin UID/GIDs, maybe someone can advise here.
