I just bought this new e-ink keyboard today in Osaka. It is called the Pomera DM30. It has a little e-ink display and a keyboard that folds up. It feels quite wonderful to type on so far. Kaz helped me turn it to English mode, and I found a website from another Pomera enthusiast that helped me figure out how to type in English mode easily with the click of one button (underneath the ESC key). It is nice to know I could type in Japanese someday as well.
