Pressure-based Page Turn Sensors

[frogplate]

Interested to see that Amazon have just announced:

1. New basic Kindle with page-turn buttons replaced by a touch screen - because physical buttons are so out of date...
2. New top-end Kindle Voyager with added "pressure-based page turn sensors with haptic feedback" as the next great thing.
   

I regularly use both touch-screen readers and one with physical buttons. Apart from the occasional frustrated swipe across the screen of the non-touch ereader I can't say I notice much difference once I'm "into" a book.

What do you prefer? Is there any future for physical buttons?
