John,Wasnt there a DILBERT cartoon showing exactly what you had described.I
guess the quality and details that you can get is going to be inversely
proportional to the size of the screen, mostly.

Dimitri,
You caused me much laughter. I would not subject a poor undergraduate to
such a situation. The fact that laptops have very limited battery life
conjured up this image of big backpack with a huge heavy battery just to
keep going and the poor undergraduate buckling at the knees carrying his
"cross". Unfortunately coloured laptops screens don't work well in bright
sunlight so I believe the professor would have to view a limited mono
screen. I have 750 councils that require a low cost GIS database and I would
like to try Manifold if it can work on one of my ruggedised 2007's You are
right regarding the limited size of the palm computers. As feedback from
clients who have purchased iPAQ units with our TUSANI complain that they
can't get enough fine map details on such a small screen, so we are
designing a ruggedised coloured unit with a larger screen. I have just
received a Grant of $65,000.00 to do so.
