H3wannabe, yes, portable GPS nav systems
are getting better and better, but if I
mount a laptop computer then I can use it
for other things too besides GPS navigation,
like Internet access with one of the
constantly evolving Internet access options.
Verizon has awesome "BroadbandAccess" through
cell phones in a few cities. I used it in
Phoenix and actually saw 1Mbps downstream
and 200Kbps upstream through the cell phone
while driving down the road. Hopefully
that system will be introduced in more and more
cities soon.
And, a MotoSat dome on the Hummer H3
would be totally sweet and provide for
Internet access even in the middle of nowhere!

(A dome or directional moving dish antenna
would look good on the roof of an H3, too,
ha ha.
