That an entire computer can be crammed into an orange sized case is not really surprising in this day and age. With a 300MHz processor, 64MB of DDR RAM and a 1GB CompactFlash Card, the Space Cube is less powerful than several consumer phones, all of which are crammed into a smaller chassis blueprint.
So that doesn't impress me. What does impress me is the gorgeous compaction of ports. SP Outs, Mic Ins, Ethernet ports, VGA support, USB port, speaker plug, etc. There's even a "Space Wire" port: "a type of proprietary interface used by the ESA, NASA and JAXA when the Cube actually goes into space." That certainly implies one leg up the Space Cube has over its competition: it is at least partially extra-terrestrial.
A neat little machine, I think. But, eyes rolled white, prepare to pull out of your consumerist lust and ejaculate your eyeteeth onto the lusciously taut belly of Dame Mock Outrage: they will be sold for as much as £1,500 ($2,769)!
