Yes, i thought about that in the beginning too. The problem i had was, that if a product isn't already in the database (outpan), you have to enter the name to add it.

I really dislike capacitive displays, especially writing on them and i think a onscreen keyboard is also really annoying.

Right now i have a keyboard which has a little touchpad, to get rid of the separate mouse.

But i also would prefer a touchscreen. Being spoiled from the nice keyboards on smartphones and tablets, i couldn't live with a PC onscreen keyboard.
