So there are some positive and negative comments here, I'd like to throw in my opinion as someone who backed it and currently owns one.
- Hardware is ok. Not super comfortable to hold.
- Pen works alright, however my goal was to use it to annotate PDFs and software issues got in the way.
- Software is absolutely awful. It's unstable, slow, and updates are slow to come.
- Crashes regularly when reading and annotating PDFs.
- Loading epubs is hit-and-miss. I have some that work alright, some that fail to load entirely. Changing pages is slow.
- Frequently fails to save your place in a document when it goes to sleep. If you're able to get it working for a few hours reading session, you might come back later to find that your progress is gone. Getting back to where you were is painfully slow.
- Support is not good. I submitted a ticket with my concerns in October, got response in January. Return period expired while I was waiting for a response.
- Battery life is merely passable.
edit: To conclude, I think that if I were to do this again I would either get an iPad or a Kindle Oasis (would have to try both to determine just how important e-ink is compared to a high dpi LCD). Either would be cheaper than the Remarkable, and you can buy a pretty sweet pen and a lifetime supply of paper with the remaining money. The iPad would probably be better for large-format PDFs, but since a lot of those have some pretty hefty margins I could probably preprocess PDFs with a script to trim them for better viewing on a Kindle.
