"Nothing i would trade my new Canon 400D for just yet...."
Thomas posted the above in our comments and it got me thinking (always dangerous).....
What *would* you trade you present camera in for? Regardless of whether you're a point-and-shooter or a pro, what features, real or imagined, already existing or not, would you trade your present camera in for?
As a brand new SLR'er (that's an awkward word), I can't imagine ever needed anything more (well, maybe faster). So what is it about the Nikon D70 or D80 (both supposedly better than what I'm using now) or a pro Canon camera that makes them "better" cameras? Is it just more megapixels? Bigger sensors?
