Just thought I would pass on this link to a company that is selling really
cheap 500 mhz Celeron machines:

These machines used to be painted either pink or blue and sold as Barbie or
Hotwheels PCs.  For $150 they are really cheap and you could get them to put
in your van (power invertor) or for a child to use.  You would still need a
screen, keyboard, etc. but this might be a good deal for some folks who want
to put a PC in their vans.
I have no financial interest in this, just thought I would pass it along.

Thanks,
