Buttons or Touch?

Buttons. Until they absolutely nail touch screens I will pick buttons as a primary mechanic but I think touch screens are good when used in conjunction with buttons.

 

I had a phone with touchscreen and when texting my thumb would always brush the cancel button and delete my text.
I hated it and swapped it for the older model with buttons.
Touchscreen needs to be thought through properley if its to work.

 

Buttons. (95% of the time)

If a game is designed such that touchscreen control is natural and fluid (elite beat agents) then touch.

adding touch screen controls to games that don't need them ( pokemon for example ) is just annoying, especially when normal button controls are removed in the process.

the most intelligent thing to do is implement both, and let the gamer choose their style.

 

I use a fair amount of both.
60% Buttons and 40% Touchscreen for DS
and 20% buttons for phone, 80% Touchscreen.
100% buttons for computer.
