I'm considering the Lilliput for use onboard.

They are selling these on Ebay:

It's designed as a mobile pc with a 40 gig HD and 1 ghz CPU. The
power consumption is around 30 watts (but no more than 48 watts), and
has some nice features. Around US$500. Any use this model or
thinking about using one I'd like your opinions.
