I’m pretty happy with Kobo. I’ve had the same model for about ten years and it’s still working great. They had color temperature changing for the backlight before it was cool. The syncing to Pocket was neat before stupid Mozilla killed it, and now they’ve pivoted to Instapaper. Plus I can install KOreader to also read stuff on my own ebook server, though I find the Kobo firmware is quite nice so I often just stick on that.
