If you ever need a fallback idea you could try turning Picwing into a monitoring tool for NOCs (network/server health) or financial systems. I think you'd have an easy time selling lots of units to both groups of customers, and there's probably a lot of other people who would need a cheap display device for monitoring purposes.
That's a great idea. Thanks for the suggestion !! We have also thought about using them as kiosks for events like conferences or for taking orders in different businesses.
Keep your prices down and your APIs open and people will do this stuff for you, and feel like great hackers for doing it. Kiosks seem like the kind of thing entrepreneurs love to dream up business ideas for and none of them seem to make much impact - that's a purely unscientific intuition.
