You can't find the touch-buttons in the dark, say when you want to make coffee in the wee morn, so you're forced to turn on lights. When you finally find a button, it takes forever to turn it to max. You have to fiddle around to turn it back down again, first click the button for the corresponding plate you want, then click a separate button to actually power it down. Again, it takes forever.
It's also impossible to train tactile memory for it, becuase the buttons are too close and too hard to discern on the dark-on-dark top, so if you try doing it blind, you'll just end up fiddling forever to find the damn thing.
If you spill something over the touch area, it'll start beeping and complaining before it turns itself off. Meanwhile the corresponding pot might have already boiled over, and you can't react in time, because the touch panel is covered in boiling liquid.
Also, honestly, I think it's actually harder to keep the ceramic top clean than a regular top. Reason: It smudges real easy, and you're never sure how much pressure or abrasives you can use without making scratches. On the old tops, you just didn't have to worry. It could withstand a sledgehammer amount of abuse before scratching or chipping.
And don't even get me started on the microwave installed here... I brought my own two-knob micro despite there already being one installed here. That should give you a clue.
