Who plays a musical keyboard on a vertical surface? Nobody.
But having had to emulate pinch-zoom in an Android emulator has made me wish I had my touch screen laptop back. Emulated touch events also don't work like real touch events, so web dev can also be a bit annoying sometimes.
So, I'm curious about how you use it. Do you have a specific use case where touchscreen made you life easier?
I have a phone with a QWERTY keyboard that also acts as a trackpad, yet I rarely use mouse mode on it. Seeing kids interact with laptops for the first time and touching the screen expecting them to work like every other device they use is also probably a sign of the times.
I understand why not everyone likes them, though. Some people prefer to disable their trackpads too, or prefer ball mice, or prefer mouse gestures over keyboard gestures. To each their own. I welcome the diversity.
