BerserkerCatSplat - fair enough; that's the first time I saw a good explanation of choice on here
Shadowness - I am mainly concerned with the reason why you chose Nikon over Canon way back when you had to make the choice between the two.
My reasons for going with Canon are (just the main ones):
The only Nikon I'm looking at is the D40 - D60 is more expensive and not that much better... I'd rather spend the extra money on glass. The Canon is the Digital Rebel XT (350D in soem countries) because its an improvement over the original 300 and the 350D (XTi) is full of bugs. Between the D40 and the XT, I found a better deal for the XT, and the D40 doesn't have auto focus built in, which limits my choice of lenses.
