I've been thinking of getting one (or something similar) since I tend to write short-term notes on stickies and leave them on my desk or monitor. I haven't found a computer based equivalent that I like using as much as writing.

This works well when I'm working 100% at home or at the office, my notes are where I work, but my company plans to have a hybrid workplace with employees working from the office 2 or 3 days a week, now my notes will be scattered between home and office. (well, worse, the office might move to a "hoteling" desk format where no one has a permanent desk, so I can't leave my notes on my desk at work).

So one of the electronic paper products seems like a good solution - write my notes in epaper, and I can access them from work (or vice versa).

Though they are still pretty expensive so more likely, I'll just switch to keeping notes in a notebook that I carry back and forth.
