Yes I have a 5 inch display as well and it is almost workable with AIS.
However have in mind that portable are typical below 2-3 inch display and a
2,5 inch display is only 1/4th of a 5 inch.....


I agree that eTrex with map is useless. By portable I am not talking
for anything smaller than a 276C screen (3.8 "), but preferable,
something like 5-7 " (Origami/UMPC like, why not?).

I do not understand why the resistance to something portable in the
boat. I know that there is more than 2 AIS solutions based on Pocket
PC (PPC) and I found it very very good, and the only restriction
being the lack of weatherproofing in any PPC.

And as I told before, I do not think that a map is necessary for use
with AIS, a radar like diagram or even the classical street like
diagram would be very useful.
