The Remarkable 2 also isn't waterproof and also doesn't have a front light (warm or cold) at all. That's how they got it so thin. It's also awful at reading ePubs but I guess better at note taking.

Kindles aren't much cheaper. Compare the Kindle Oasis to the Libra. All you really get is a metal case for an extra $100. And the stores are pretty similar in size with the exception of like self published books which IMO are worth stripping out of search...
