i saw these a while back, dont think they would have enought power to be a media playback system.
Q. Are they suitable for Linux and PXE boot environments?
A. The units are currently only available with Windows CE and the only PXE boot option is to boot to another Windows CE image (for more information regarding PXE boot click here). Linux implementations are being investigated by Chip PC's R&D department but there are no timescales for this as yet.
Not sure how they would be locking out outher PXE images, but i guess it could be worked around with a bit of hacking.
They're not cheap, Â£349 for the one with a 500Mhz CPU and DVI. or Â£209 for the low end one.
