I've loved all touch devices since the original iPhone. Never looked back. I view buttons as both inflexible, and liable to break.
As for capacitive vs. IR, capacitive is definitely more responsive and can do stuff like multitouch, but on an ereader IR is good enough. Plus IR works with gloves (smartphones can be a pain in the winter). I'm interested in how Amazon was able to make the new Kindle capacitive without making it very fragile and/or reflective (see: glass)
p.s. I'd echo setting page turns to tap. With that I find it just as reliable as a button, and it requires less effort. With swiped on I'd always end up turning the opposite direct I'd intended because my brain was wired for something else that works the opposite way.
