I'm typing this on my Boox Note Air 2 Plus. I absolutely love this device. I usually use it without the backlight, but sometimes at night I'll use the backlight and the adjustable blue light filter is an absolute must. This is my fifth or sixth E-Ink device, and probably my favorite. It's an Android device, so everything that I was already using works on it. Notably Firefox when properly configured, and Ankidroid.
