I have a Boox Nova Air. It’s a 7" B&W e-reader. It’s nice to have a boring Android tablet that also happens to be an e-reader.
I wouldn’t recommend ePaper for anything but the very lightest of web browsing. The like refresh rate really is a lot to take in.
Using the pen is nice. It feels a lot like black magic, really. It’s just like drawing on paper.
If like to get a colour version to read comics, but let’s face it, I can’t even remember where my current one is, let alone the last time I turned it on…
My very large organisation has Gimp available for basic image manipulation. I’ve tried to get them to use Paint.NET instead, but nooooo… Apparently we like hitting nails with jackhammers around here
