This one seems to run great, touch screen probably helps a lot. Only complaints seem to be small text on screen:

I also wasn't able to adapt to first person shooters, after a life of playing with mouse, it is almost impossible for me to not feel that gamepad controls are clunky.
Is it with a touchscreen or knobs on the side?
I think I would still miss a mouse for precision and speed with that ..
However the screen is 7 inches and text in games like this or early Fallouts is too small for me, so I planned to use SD for them but resigned.
Unfortunately, PST is an early iteration of the engine and I had problems with inventory manipulation --- not sure if that was ever addressed.
Similarly, for FPS the gyro can be used for additional aiming and even set such that it's only enabled when one of the joysticks is touched (via the capacitive receiver).
