This is a rather silly question, because you are going to get very bias answers. I'm a Canon man so I say T1i. Nikonians will root for the D5000. In the end you will have a tally of people that read this thread detailing who shoot Canon and who shoot Nikon. Either will work, but you aren't deciding between these two cameras. Rather, you are deciding which of these two companies you will use for the rest of your life. Both are excellent. You can't really loose with either. Nobody can tell you which is better other than personal experience. Your own personal experience with both cameras. Rent them, borrow them, read about them, and decide which company...or family rather, that you want to marry into.
