What aggravates me is that with each new Kindle we might get newer technology but unfortunately we seem to be getting fewer of the features we have long had. I'm also angry that few reader manufacturers seem to listen to their customers' requests. Probably the most requested feature from eInk users is "GIVE US MORE FONTS"! Some manufacturers have done this to various degrees, but Amazon continues to think we are happy with the three original fonts. And one more gripe, what is up with all these different interfaces? I understand that eInk models are physically different from one another and that they have a different OS than the Fire, but geez each one is way too unique. Amazon should pull their head out of their corporate fat a$$ and at least try to make the interfaces and feature sets for the K4, K5, K6, and various OS apps similar. And get Whispersync working like it was promised it would a long time ago!
