Casting my mind back what feels like decades but is actually only about 10 years, and there was the iRex Digital Reader, which was a device somewhat bulkier than the ReMarkable but did basically the same thing. I had one and loved the idea of being able to read using e-ink, and to write on a paper-like surface. My work flow does not include enough pdfs to have made it a real necessity - it remained much quicker to use real pen and paper, and lugging those around were also less of a hassle - so it was just something I wanted to try out. I dropped it and the screen cracked, which cost an absolute fortune to replace, but my main concern is that the ReMarkable, ten years later, still has similar limited and clunky software. One would have thought that things would have moved on by now. Seeing that, and with my iRex experience, strangely, I have no desire to buy or even try the current incarnation of the ReMarkable, which, given my CRIMPing tendencies, says enough :-)

iRex, by the way, went bankrupt in 2010 ....
