No but the kindle I picked up for $30 can and, from the sounds of it, better. Is the ReMarkable $540 better than a kindle and a notebook?

If I really need to annotate PDFs, is the ReMarkable really $600 better than the tablets they're literally giving away for free these days?

If I really need to run arbitrary software on something that I can also use to read and annotate PDFs, is the ReMarkable really competitive against an entire Core i5 laptop with a touchscreen and stylus?

Yes, the ReMarkable has a one of a kind writing experience. I'm not arguing it's not better in certain aspects than the alternatives. But the premium here seems absolutely nuts.
