Touch-based buttons feels like a huge step backwards. Have we learned nothing from having to use touch phones for the last 12 years, either that or everyone is much better than me at not missing touch inputs
3/4 of the reason they're touch is being 'cool' and none of the designers ever cooking a meal in their life.
Its definitely easy to clean my entire range being a flat piece of glass, and personally I've never had any problems with sensitivity on the buttons. Plus, that whole cook top is then still useful as a counter top as even the glass is only slightly raised over the rest of the counter surface. In my experience the glass top range I have has been wonderful, and I was originally planning on tearing it out and putting in a gas unit. I've since second guessed those plans and will probably keep the range for a while longer, no knobs has actually been pretty nice.
