The gumstix is running Linux, and doing anything real-time in Linux is problematic and non-trivial.

You're really better off using the processing power and memory to figure out what to do, and let more dedicated hardware (like an AVR) deal with hard real-time stuff like servos and such.

And yes, USB is a bus, so you can have more than one USB device plugged in...

Actually, starting with 2.6.20 doing realtime is much easier under linux.

You can even prioritize threads to have higher priorities than interrupts.

And yes USB is a bus, but it's point-to-point. To talk to more than one device requires using a hub.

This board also looks interesting at 99 Euro:
