My Remarkable 2 has been worth every penny. I bought it as a more modern solution to a notepad which saves me from carrying around 3-4 at a time when travelling. It does the trick well and is a pleasure to use.
Where it really excels for me as a nomad is that I no longer have to run around lounges looking for printers when I need to sign some contract or KYC for a bank. I just mark up the PDF with my signature and details and send immediately. It saves me a good 15-20min each time which adds up.
