I must say, it surprised me when I realized that these games work beautifully on a tablet. They are all single press single function keys in game and it just works.

The only drawbacks are the lack of a keyboard to type names and the fact that you can't scroll (mini-map is how I move around).

I love it.

(EDIT)
Bit soon since my first post, but I can scroll!

Asus Vivotab 8 with a Wacom pen (the hovering action of the pen is what acts as the mouse curser and scrolls). It's glorious.

Now, gotta go mine my mountains!
