Having seen the Windows side of it, I am not worried to much about the drivers - even Realtek built-in soundcards can pull off decent latency. Touch screens, on the other hand, are a problem -- they add input latency if you want to use the screen as an instrument/controller, and that's what a lot of music apps do (virtual keyboards/drum pads/etc). Last time I really tried those, every single device was atrocious in that respect (both iDevices and Android)[1] -- keep in mind that total latency from touch to sound should be under 10 ms to be really acceptable. And things haven't been getting better until recently. Short of music equipment, the trend for everything has been to get more sluggish[2] Razer Phone and iPhone X might change that[3] if others follow suit, so I'm hopeful (both feature 1/120sec touch latency, which is OK).
