GPS & Computer
I would highly recommend a Panasonic Toughbook. I purchased a used one over 6 years ago, and it just won''t die. There aren''t as many bells and whistles as newer laptops(I can''t play DVD''s, only one serial port...), but for reliability they can''t be beat IMO. I use it constantly for navigating, Winlink email, digital pictures...I can''t say enough good things about it. It was pretty pricey even used, but well worth the extra dollars. Another great feature to have is a docking station to attach the GPS, Ham/SSB radio, DC power supply...which then gives one the ability to remove the laptop at a seconds notice without having to unhook all the connections.
