Amazon just refreshed their colorsoft kindles with Kaleido 3 so this is an interesting development. I wonder if Amazon had a heads up, I would have buyer's remorse right now if I bought a new colorsoft kindle recently knowing that there's a better version of the screen just around the corner.
I feel like amazon tends to wait a couple of years before using whatever the latest e-ink screen is and claim to do a lot of customization and calibration as compared to their competitors.
