Glad you like the photos. And it's a good question. Now for my long answer...
We talk a lot about "convergence" these days. Digital photography, for example, is the convergence of computers and cameras. But nearly every type of photography is the result of convergence -- typically man and machine working together to produce compelling pictures.
A great camera will not make you a great photographer. But a lousy camera will frustrate a good photographer -- and I believe will have a negative impact on the pictures he or she takes.
So what's important, IMHO, is that you find the right camera for you -- one that you can bond with, becomes an extension of your vision, and is a complement to your talent. Sometimes this takes a while, and you have to go through a few cameras to get there. (At least that's what I tell friends when I show up with a new one in hand!)
One of the reasons why I wrote this review of the EOS 10D is because I believe that SLRs are easier cameras to bond with than most of the digicams available today. But digital SLRs have been too expensive. The 10D is expensive too, $1,500 US. But for photographers who miss having that SLR "soul mate" they left behind in the analog world, the 10D may prove to be the "other half" that many shooters have been waiting for, including myself. Nothing against the rangefinders I have. There are a couple models I've really bonded with. But instead of being my only digicams, I can now use them in situations best suited for their design, such as travel and wide angle photography.
A photographer who likes his or her equipment tends to take better pictures, regardless of camera brand or price.
I like the EOS 10D and enjoy shooting with it. I look at my pictures closely on the computer and adjust them if I have to. It's the convergence of many factors that make a good photograph. Which camera you choose is part of that equation, but it's not the only factor.
