Good to hear, fuzzy.
On the toughbooks, through my work I've been able to get myself a hold of a Panasonic Toughbook and even one of the new ruggedised Motorola Android tablets. Very nice units that can REALLY take a beating. Expensive
but nice. The Panasonic was running Windows and I only had it for a week of testing, so I can't speak to it's use in a boat. With that said, you've kind of incentivised me to look at getting OpenCPN running on an Android tablet. I can see that being very sexy.
