Re: Semi-Permanent Onboard PC?

I guess it comes down to what is sufficient. I built a VIA M10000 system
for this purpose and am not happy with it. You are going to be very hard
put to compete with one of these 10" Pentium M based laptops that with the
monitor are as small if not smaller than my ITX system, quieter and as
energy efficient. Put it into a port replicate (or not into one) under the
chart table or in a cabinet and you have the same thing only faster and you
can pull it out and take it to the internet cafe.

For now, I am using my monster laptop with the WUXGA display. I don't
intend on using a PC for navigation or anything critical because I don't
trust them enough. I use them for route planning and all that fun stuff.
And least you think I am a technophobe, I'm not, I am a recently retired
software engineer.

That said, I am a PC junky and can't resist toying with all this stuff.
Even not using it for critical functions, I feel the need for at least two
PCs on board if not three. I might start quivering and shaking if the only
one I had died.

By the way, did anyone mention printing? I am using one of those Canon
portables, can't remeber the number right off, but so far it has been
awsome. Battery powered and with bluetooth it lives in a cabinet and when I
need to use it, just pull it out, pop it open, turn it on, put it on the
table with some paper and I'm printing. Thirty seconds from waterproof bag
to printing.

I wish you luck on this poroject. I may be a customer some day.
