OE2X, I definintely am looking forward to hear your view on the Nexto. Generally I take my laptop with me everywhere but USB2 is going to take a long time to download 4GB card. If the Nexto is nice and fast and reliable (and long enough battery life to download 4GB card at least a couple of times) it would be nice especially when surface interval is not long or when I am on a daytrip boat rather than a liveaboard.
