Sony’s mammoth 13-inch Digital Paper tablet, essentially a huge Kindle you can write on, is still a pretty rare sight, but I’ve always had a soft spot for it. So I’m glad the company is doubling down on this unique device type and making some significant improvements with a new model.
The DPT-RP1 replaces the DPTS1 — catchy names, right? — and makes some changes that its users will certainly appreciate. The screen itself, built with E Ink’s Mobius display tech, has been upped from 1200×1600 to 1650×2200, which should make text considerably clearer (206 DPI — pretty good). The increased resolution doesn’t seem to have affected the battery life, though: like other e-paper displays, it’s super-long, at least a week or two.
The touchscreen layer has been improved, as well, and the texture of the surface; e-paper displays aren’t very responsive, so anything that can be done to improve that experience is welcome. This has presumably enabled the new note taking and annotation features the device has.
And, of course, the hardware itself has gotten a fresh coat of paint: it’s the same weight, but the design has been cleaned up and the bezels are slightly thinner.
