If you are rolling your own I would advise a Soekris net4501 (US $173 new) over
any netbook for several reasons: cheaper, more rugged, better solution overall.
It all comes down to requirements, budget, and who the user is (which drives
the first two). If I were doing a system for myself, it's

I had suggested the same thing. In fact I'd argue not having an NTP box is
