Okay. Here let me drop into the conversation that I'm a
heavey user of the dictionary and highlight feature. With this in mind, will an IR device as good for me as a capacitive one? If IR is so good, then why do manufacturers distinguish between models that they add strictly IR only to their cheapest models, and capacitive touch to anything a little more fancy?
On a side note, maybe I should get a Kindle 5th while I can. It still has buttons, and the one clearly benefit it has over my aging Kindle 4 is the brighter screen. Do you know some secret store where I can still get it cheap? Some places I have found sell a new one for much higher prices than it was sold for in its heydays. Smart. In the US or Europe. Am I a caveman for still wanting a device with buttons?

(For reasons and details, see the linked thread).
