Waterproof IPad Cases?

Well, it's no surprise that the new IPad from Apple offers a wide variety of GPS navigation, mapping and weather tools. Many have been ported over from the IPhone, while some apps have been re-worked to truly take advantage of the larger screen size. The other day I had this strange thought that my IPad might be a fantastic replacement for the old Garmin on the deck of my kayak! Can you imagine!?

I hate navigation

Let's just get this right out of the way. I HATE navigation. I mean, I LOVE maps and charts. As a teenager I used to stare at maps for hours. Even now I enjoy examining them and imagining how to get from point A to point B by car or kayak. What I hate is academic navigation. The bit where we toss a bunch of labels on common sense ideas, get all worked up measuring this and adding that to come up with some magical, algebraical solution to paddling across a bay in conditions where most of us should never leave the beach.
