This is Enrique from picwing. In addition to the larger display, the picwing frame runs on a faster hardware platform, supports Actionscript 3 for application development and doesn't require the user to go to a different computer to customize and install widgets. Eventually we would like to release an application store (running on the frame itself) for people to install new apps for their frame. We are ourselves big fans of the chumby and we have tried to learn from its advantages and shortcomings.
