As a result there is only one layer and no effect on readability. My PRS-650 has a beautiful clear screen with no glare. The screen's mildly rough texture even seems to prevent most fingerprints. I can see a few if I angle the screen just right into a light source, but otherwise they aren't visible, not like the tons on my iPad.
I find a touch screen intuitive, not counter-intuitive. For me they're the easiest way to turn the page and nothing beats double tapping on a word to look it up in the dictionary.

At the time I commented, I had yet to use a 650, or really look them up. They're very nice. I seriously /hope/ there are still two layers, though. Something to protect the e-ink screen; I don't want to pop microcapsules with my nails.

I expect they will eventually. Something like the newest Sony technique so it doesn't affect screen clarity.

Given the ingenius IR array technique, I'd hope so. It's pretty nifty; But I'm still curious.
