I was reading the "about" section of the watch and it occurred to me that you can read quite a fair amount of information. It would be kind of neat if there was a folder you could upload text files into, and then display them. It's a bit unsafe to have your debit card PIN, but you could have your phone number there, contact information or something like that? Perhaps even a simple shopping list?
Is it already possible to edit the files shown on the "about" page, and use that for the information? This might seem like a crazy idea, and I won't be offended if you think it's dumb :).
