It would be nice to see a version that has some kind of IO capabilities of a more basic nature (like parallel port, UART, IO pins, maybe even ADC). And I say that not only from an robotics enthusiast's view point, but also from the view point from which the designer speaks: It's all fun and games to create a program that prints some lines on a screen and do something very clever, but when you write a program on a computer screen that makes an actual change in the real world (moves a motor, pulses a LED, torments your cat by following her all over the house), that's where the magic happens.
I'd really like to see that. Also, think of all the computations an 700MHz processor could do. Studying industrial robots in college, inverse kinematics, path generation and following and constant torque applications spring to mind...
