Most ereaders have a recessed screen regardless of whether they use infra-red or capacitive touch.

A recessed screen is protected by the bezel, but a flush screen has to have an extra protective layer like a tablet. It seems to be that exra layer that causes the reflection problems.

The only advantage of capacative touch over infra-red is that capacitive can accurately detect three or more concurrent touches, whereas infra-red can only accurately detect two. However that is not really a very useful feature for an ereader.

An advantage of infra-red is that you can use something other than your sweaty/oily skin to touch, such as a fingernail, so the screen doesn't have to end up covered in fingerprints.
