How would you improve tablets?

Yes, you can improve them with specs, but what about something else? Something that adds to what you could use your tablet for?

My improvement:

The Dual Screen.

I would like to have a better way of integrating the tablet with other screens. Instead of just mirroring, I would like to keep 2 different screens.

For example, if you have an external monitor and would like to use a office program the program could show up on the external monitor while your tablet becomes a full keyboard or keyboard + touchpad for the screen.

If you're into games instead, it would be cool if the tablet could show additional info on it while playing on the external screen. ( in RPG's you could show your inventory or something, in shooters, maybe your weapons or kills/deaths etc. )

In what way would you improve your tablet?
