I want to get my hands on one, but I think it's pretty good from the specs.
I'm biased because I have 3 canons already
But I like the anti-dust measures and wish my 20D had them !

I wouldn't take it fishing, as it's not as waterproof as the 1D pro bodies.
But then I wouldn't take £2-4,000 of body to sea either
Photo-John was reviewing some waterproof, shockproof cameras that he uses for biking that might be good for going to sea...

You may end up with two cameras eventually, unless you're braver with your SLR than I am !
