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.

I'd think you are right, I don't know enough about Android internals to tell you why It feels slow. I speak from an end user pov here.

I love the hardware of Android devices, they are way ahead of expensive Apple offerings... but when you actually use the devices they feel much slower than even vintage iOS devices. It's shocking.

And I fear that multi-user support will increase this slowness, actually... I'm pretty sure of that because I dealt with multiuser issues during my career.

I mean, the device will have to store the state of the session when you switch between users (running apps, configs, connections, ecc)... Android has to keep that state in memory somehow, in RAM or swap it to the flash memory... It's not a minor concern, It can be very resource hungry.

Then you have the file owner/permission issue. You don't want that your files can be modified by another user. Android will have to implement that too.

That's why I think adding multiuser support to a mobile OS is a big fat stupid idea. Good multiuser support is a complex thing. It's not trivial nor "free". KISS.
