I've used the DM100 for ~5 years now. It's an entirely different feel from a general-purpose device /w foldable keyboard. For starters, it's "always on" -- when you open the case, you're in the text editor and can start typing immediately. Second, it's a distraction free device: there's no wifi, no checking email, no browsing. Third, it's physically convenient, you can put it on your lap in a meeting or keep it on the table top (the display is not tall), taking notes without disrupting flow. Lastly, it uses easily replaced 9-volt batteries, which last a few weeks of occasional usage.
There are two quirks in the older model I have. First, when opening the cover, it always starts in Japanese, so you have to press a key to get it to English. Second, some of the characters are in different slots; e.g. the apostrophe is inconvenient. Third, the keyboard is a tad scrunched.
