I just had to ask this, in terms of build quality, lens compatibility, lenses, and cameras, which company is more "popular" per say... I know this is an open ended question, but I am just curious to know what opinions users have. Before buying my first DSLR, I need to decide between the Canon XTi, or the Nikon D80. This decision is very important, I do not see myself wanting to spend extra money in the future to switch systems. I want to buy a camera that will last me 2 or 3 years, and then if I do get into photography, that I have alot of lens choices available. Also, any news on the D90? release date? Thanks.
