Running the risk of dragging this off topic.
I have a D700. I got it last year and did update my website. Although since I have not dived with my one yet (for the Wetpixel review I borrowed one) it doesn't really feel like my camera. I have not done anything with it yet, so have not been able to post anything.
I was forced into upgrading because my D2X is on its shutter limit and with 6 weeks underwater in the next 7 I decided I needed something more reliable. I would have preferred a D3X, but I am not rich enough. I actually think that the D300 is a better UW all rounder to the D700. But the D300 is so similar to the D2X (except at higher ISO) that the D700 seemed to offer more new technology to explore photographically over my existing kit. The chance to expand the types of images in my portfolio. Plus with travel plans to do lots in the UK, Norway (where they catch both whales and fish) and Canada - a high ISO specialist seemed like fun for 6 months.
I'll be quids in if the D700x fits in the same housing, but I have a nagging doubt about that one.

Back to the intern - their job would simply be to follow the sharks with the pole cam - and I'd press the button at the right moment. Although, because Jeff is on my JASA Oceanic White Tip trip - maybe we can just use his housing!
