Time diversion versus what?

The lack of dedicated controls is only a negative for games that require precise inputs (like classic arcade games). There are so many fantastic games that don't require that at all. Strategy, turn-based RPGs, puzzles, adventure games, etc. For certain games, a touchscreen can blow dedicated controls out of the water if the interface is designed well.

Yup, especially for strategies. It's much easier to touch the position with your finger then having to drag mouse across the screen.

That only works on a simple boards. Chess is 8x8 and feels cramped on a 4" screen. Go at 19x19 takes scrolling or zoom then click which slows down input. For a more complex board you end up being vague or spending lots of time fighting the UI.

Exactly. Some games are perfect for touchscreen, like Temple Run, Candy Crush and Subway Surfer. I don't think that's the real problem with mobile gaming.
