Here's my thinking: If you're totally new (which I'm assuming since you said, "beginner"), why start out with something so expensive? I started out back in 2002 with a Canon point-and-shoot camera, the ol' S30, and it served me very well for about 2-3 years. By that point, I'd advanced enough to where I needed the flexibility and control that only an SLR would offer, so I bought my Rebel, which was the 350D at the time (Rebel XT, I think). It, too, served me very well for 4 years. It was only in the last year or so that I felt that I was again at the point where I needed even more control and features that a better body would offer, so I was going to get the rumored 60D when Canon came out with the 7D, which is what I bought (and am very happy with).
My point is that if you're a beginner, you may be enthusiastic and all, but if you get a DSLR with a bunch of functionality that you won't know how to use, you may feel overwhelmed, and for that and possibly other reasons, you may decide that you don't actually want to pursue photography much. Then you'll've wasted the money when you would've been happier with a more portable and cheaper point-and-shoot.
