For what it is worth there is a listing on eBay that may be of interest to some members. I can't seem to get the link to post in this message but if you go to eBay and search for item #170030254932 it should come up; the seller has more than the one item in his "other listings".
(His item description is "Rugged Marine/Military Chartplotter GPS
In my opinion what I see as good points of this unit are
2)it would seem logical that it is rugged
4) It is not dependent upon anyone's proprietry charts
. NOAA charts
can be had for virtually free
6) 6 gig will hold a heck of a lot of charts and programs. (My nav program for ALL British Columbia
charts and os fits on 3 cd's. All US NOAA charts fit on 6 cd's)
1) there are no disk drives -software will either need to be loaded via usb flash drive, LAN, etc (Not a big problem -just annoying)
3)Windows 98 Operating system was not the most stable (but it was livable)
4)only 128 meg memory
reciever is not included (you can buy one for $50 on eBay or better yet you can buy Microsoft Streets and Trips 2005, which comes with a reciever, for $60 and use the tablet in your car as well)
It would seem that this is a low power consumption
unit as the seller claims the charger
only draws 36 watts.
Anyhow I have put my money
where my mouth is and bought one (but I have a Bannana box full of computer parts
that I must have thought were 'good deals" at one time so there may be a down side that I am not seeing.
