It's a good point you all raise. Many years ago my dad bought me a Canon AE-1 SLR, my first "real" camera. I loved it, still do actually. When the time finally came to buy a digital SLR there was only ever one automatic choice, the Canon 400D. Then I went to a shop and tried it. Man, was I disappointed. Too small, way too small. I was gutted. I went to another shop which had the Pentax K10D, which, pound for pound, was far better specced. Same problem, it felt uncomfortable in my hand. The same shop had a Nikon D80 and I (reluctantly) tried it out and wow! What a revelation. It fits like a glove. There really only was one choice.
Since then I've never once felt I had a "better" camera, just one more suited to my hand. And that's enough really. As Bob says, as long as you're comfortable with your camera nothing else really matters. I certainly wouldn't be able to distinguish between the same scene shot through a D80, 400D, K10D or a.n. other.
Good luck to you. We're looking forward to seeing your results.
