Very HN question, but are they hackable? I'd love one of these as a daily calendar; I've used an old/decrepit Kindle before for the same sort of thing, but something like this would be much more attractive. I could assemble something myself, I guess, but I've got other projects taking up time and don't mind paying a little bit to turn the physical assembly problem (I'm bad at) into a mostly software problem (I'm mildly better at).
