I know I'll probably get run through with someones light-sabre but I've been researching this topic myself for a few months now. Not being a total computer geek and not wanting to spend oodles of money
...here is what I came up with.
I ran into a guy with the sistership to mine and he looked as poor as I am. here's what he had.
Acer W-510 PC Tablet, I believe running 7 or 8. He chose it because the adapter was 110ACV to 12DCV. So he plugs it into various cig-sockets.
USB hub (good quality, gold contacts)
USB to mini USB adapter. (for adapting the tablets mini the larger USB)
Wireless mouse and keyboard. (stops gooing up the screen)
Garmin GPS puck
with USB end. (not a cheap
I priced it ll out on Amazon...$450. That is with a refurbished PC Tablet. He runs Open CPN on it and his AIS
also. He demonstrated it to me. Looked pretty slick.
He put velcro on the back of it, so it can stay put in various places as well as a docking
port for it.
I'm the same as you. I want a Nav system that I can use for Internet
also. Seems like the way to go.
