Linfiny (a company created by Sony, E-INK and Wacom) seems very interesting. They will be releasing some new models this year, including color e-ink. These are the successors of the Sony Digital Papers, which I think are the best note taking devices. I bought mine in 2018 and use it almost every day. The addition of the Wacom layer will be great, because the original stylus was not so great (although it did the job).
