It has a "plain" USB 2 host/client port, but it seems that the PHY is rubbish and doesn't work, so they've stopped fitting the connector. Rev C (Nov 2008) will use a different phy and will work.
It does (as Mark pointed out) have USB OTG which will work as either host or client at super high speed.
The processor itself has a TI DSP integrated into it as well as a POWERVR graphics engine, in one word, ridiculous!
Hopefully ours will turn up sometime this week and I'll be able to have a play!
The current "user submitted projects" on their website are, well, quite frankly crap. Maybe there's scope here for something....
