It feels like one of those things where if you think you want it and you can imagine how you'll actually use it, you'll use it a ton. I had been on the fence about getting an e-paper device for a long time. When I heard the details on the Daylight Computer, I knew it was exactly what I wanted. I pre-ordered it within hours and I have probably used it more than any other devices I own since it arrived a year ago :P
