I upgrade for new technology, but with an eye toward getting value and longevity out of my tech, and getting noticeable improvements in my user experience. I upgraded from the Nook Color to the Nook HD+ mainly for the larger screen and greater pixel density, because I had uses that would benefit (comics and magazines). A device appeared with a feature set relevant to my needs and at a decent value.
With eInk, I entered the market (just this past week

) because of new technology. Until the latest improvements in pixel density, refresh rates, and integrated lighting, the other benefits weren't enough to lure me away from multipurpose devices. I'd been eyeing the current gen for a while, and with a couple of long reads coming up that I knew I'd want to Whispersync with Audible (
The Stormlight Archives), I sprung for a Paperwhite.
