Interesting product, I just can't see getting one without the ability to save the "document." But then again I am more geek and less creative. (Apparently a save feature is on the docket for the next generation. Let me plug in a USB cable and I could be happy.)
It's an electronic etch-a-sketch! I could see an application for a larger one, say in a small restaurant for daily specials. That would be something you wouldn't want to print and you'd change it often. But for now, it's just for doodling or reminders; carry in the car or keep in the kitchen to make a note, or take phone messages for family members. Cute how their web page automatically opens another browser tab on Amazon to buy one.
