There are a few with knobs but not many. More options there would be good and I think dials are still the best interface. That being said the good touch ones aren't as bad as I expected.
I have used a few different flat panel ones and the miele one my parents recently installed was tolerable despite the fact it was all touch. The lights for the buttons are bright, they work even if a bit dirty / wet (not in a puddle but don't need tho be clean), and it doesn't panic if you move a pot over the buttons.
On the other hand, I've used an Ikea one a bit (my partners mum has one, and she lives at home). It's so shit, the buttons are dim and hard to see, it panics if a pot goes over them and they don't work if a little dirty.
Overall, the touch ones can be bad, but if your go with a well made one like miele they're actually okay.
