The Nano-ITX does look really cool. There are a few downsides, though...
- Only expansion is via Mini-PCI
- Uses SODIMM (Laptop) memory
- No Firewire onboard
It does, however, have USB2, SATA, and LVDS onboard. I don't think there have been any benchmarks done yet. I've only seen pictures. Oh, and the "N" does stand for Nehemiah.
