The 790SW is an excellent toughie, and a lot better image quality than the 720/730/770SW range it replaces.
I have been using a 720SW for some time, including underwater and literally chucked around in the cockpit.
Yes there are better picture quality cameras in the proce range, and yep the XD picture card memory isn't as good as SD cards but you get a seriously tough camera and stick a slick skin on it for the extra protection.
I can't lend you the 720 to try as it has gone with Josh in his backpack for 6 months in Aus and NZ.
and that's a good deal on it..........
