Business applications
I always look what people do with gadgets. Background: A gadget is a part of a computer function that is build into a unique product with the effect of easy-to-use. Easy often simple means: instant and mobile. Look at game consoles or the iPod. The first is cheaper and faster to use for games, and to switch the computer on just to listen to music would be too much..
Thats why I think the ZDNet video about "Three ways to use the iPod at work" is interesting. Maybe you have an idea how to make these functions wearable:
CNET's Veronica Belmont demonstrates how to transform your iPod into a voice recorder, a laser pointer and a language translator–giving you the business justification you need to use the music player at the office.
