Wow I'm totally the opposite, I don't miss the guess'omatic focusing, the metal framer for the macro, the 36 exposure waiting for a few days (weeks) for the Kodachrome to come back, the temperamental advance lever design, etc, etc.
Now, if they can give me instant reviewing of my work, 200+ images, through the lens viewing, interchangeable lens that goes from fisheye to radical macro, that can shoot both video and still and has good ergonomics then I would buy it right now and then and... but wait a second here, hold on, I actually did, its called a DSLR in a housing.
When Nikon and Canon came out with auto focus SLR, the were building the coffin for the Nikonos, when the Digital SLR got introduced they where nailing lid on, it would make no sense for Nikon to get a dedicated underwater specific camera system such as a Digital RS nowadays, too much of R&D for the return on their money, they would rather sell off-the-shelf DSLR to users who put them in housing later on, no liabillity, no shortlived digital camera body being left behind because technology made a leap ahead. and then the compact revolution came in, and that cremated the Nikonos concept before bulldozing it under its proverbial 6Ft under.
Don't get me wrong, I still have a couple of V's and the whole I, II, III and even this despiteful excuse of a camera, the yuckinos IV, and I am very fond of the time I spent with them and still use images done with them, but I don't miss 8 track cassette, rotary dial phones or VHS either.
