Diki,

There's no need to hate if You dissagree, after all, that's what the forums are for (among other things). :-)

My turn to dissagree now. ;-)

If You ever saw somene who properly learned typing then You know for sure that You don't need to see the buttons in order to be able to type very fast (faster then those who 'search every letter on a keyboard'). I have yet to see somene doing the same thing on touch-screen (or sensor keyboard which is quite similar).

When You use Your keyboard for a some time, You remember position of the buttons, and You can use them without loking for them with Your eyes (afeter all, You are probably playing the keyboard without watching Your hands).

As for the tactile sensation, it is not the same es tactile feedback, the first one gives You just information that You touched something, while feedback gives You information that You performed action. Of course, there are different kind of buttons, and lower quality ones are usually without feedback (using plastic foil instead of mechanic parts), but buttons with good mechanics gives You exact information wheather you performed action or not.

For a touch screen it would be great to have some feedback system like vibrating device, that would trigger when You press a key (silent because audible systems, like the one Fran mentioned, have no use when playing loud music).

As for the reliability of touch-screens, I haven't use any on keyboard, but from expirience with other devices (PDA, notebook, mobile, POS terminal) I know for sure, that touch of the screen doesn't equals with performing action.
