Hand held PC that can run Rev?

[David Bovill]

I am looking for a small portable hand held-type device that can run Rev.
Ideally it would be an iPhone or iPOD Touch type machine as I need to be
able to show video in an interactive environment.

I've been researching small PC's - Single Board computers - but was
wandering if anyone has found a suitable piece of hardware? Something like:

Or maybe something you can put together based on:

Anyone done a project like this?
