I'm a juicebox owner who just re-visited this site by a recent digg.com link. (You've been warned.)
I understand the goals of getting better and open audio, graphic and video formats, but are their other applications you're looking for on this platform?
Frankly, I was disappointed when getting mine to find the strict image format. I was hoping to drop my camera's jpg loaded SD card in and start browsing and deleting. It would be fun to be able to hook it up to my box and control the display from a PC, moving beyind the standard text lines boards used for status and other things.
With the feeble controls, is anyone anticipating a game emulator?
Is the serial port effort in hopes of a device controller?
