The BeBox is based loosely around the Apple Macintosh design. It features two 133Mhz PowerPC processors. The two sets of yellow lights on the front of the BeBox represent the CPU usage of each processor!
The Be is currently running BeOS. BeOS appears to be a reasonable operating system, but application development for the BeBox hardware seems to have stalled. The BeOS release for the Intel architecture appears to have a much larger software base. As it stands the Be lacks much in the way of useful software.
