The ARM11 cpu is too old, I wish they used at least a Cortex-A8. ARM11 has a virtually addressed cache with aliasing issues that requires all sorts of hacks in linux kernel, it will require old compiler flags and lacks other ARMv7 features. It's the cpu from 2005. I wonder what the price difference would be if they used an A8.
There are some similar cool open hardware projects sponsored by TI. They have better specs, although their prices are quite a bit higher. I don't know if it is because they do lower volumes, the chips cost more, or price just wasn't as much a concern when they were designed.
The beagleboard-xm has an A8, 4 usb ports, and 512 ram for $150, the related beaglebone has arduino like pins and an A8 for $80, and the pandaboard has an A9, 1gb ram, and wifi for $180.
