For those who want a hardware+digital writing-focused experience, I'd recommend the Kingjim Pomera series.

We bought a Pomera DM250 a few months ago while in Japan. It's really sleek and feature-rich compared to western-built writing-only devices which are limited, more expensive, and bulky. It opens up directly to a word processor; runs Linux under the hood.

You can buy them via ebay as well if you're not in Japan.
