Oh wow. This is very interesting for comic creators. Most drawing tablets work great and are fun to use, but they don't feel like paper. It looks like they are utilizing the e-ink technology that you talked about in a prior steemit article. I have a Cintiq right now which is cadillac of portable drawing tablets, and it can last maybe 2 hours unplugged and is pretty heavy. This product appears to be TRULY portable in that it can last days without needing a charge. If the Steemit community focused its collective brain power on this, it could become the end-all drawing tablet.
