Haha, no Kyle, not right this minute anyway....

Barney, if you buy the optional heater (being that the Rotax is liquid cooled) the cabin heater is supposed to be amazingly effective. Rick, I like your input, and I realize they have several revisions of hulls over the years. The factory doesn't recommend over 12" waves, but that would certainly be a comfort level item. The gross weight is also higher on the new models. I wonder if the braking system is still the same? Their site says hydraulic disc, so I would have been surprised if that also didn't mean differential.
The Lake is much more under powered, and from what I head, not particularly nimble on the water. The epitome of water handling however is the Icon A5, but I don't have $130k to throw around, and quite honestly it's under powered for high altitude operations.
The Searey isn't low wing per say, but they don't sit terribly far off the water so true, you'd have to be a bit mindful of docking. If you waited till the water froze and were careful of really rough ice, I think the wheels would work fine on frozen lakes that are large enough, and with the tailwheel configuration, you could still slow down.... kinda.
