The kobo colour goes for less than $160 regularly. It is water proof, has front ligths, usb-c, and it can display color. I’m considering it for an upgrade from my, bought used 8 years ago, kindle. With Kobo, and ereaders track record in general, it will probably last twice that and still work. I consider that extremely cheap, specially in a market that usually expects people to dump a thousand dollars every two or three years for a phone. E readers have some of the best cost to utility ratios of electronics.
