Problem with new photographers: you don't really know what you're doing with it yet, so you don't really know what you want (for example, is the type of lens you want available on that system? Wait, you don't even know the kind of photography you're doing, so how do you know which lens). A camera is a tool, you know which quirks you want when you're good with it.
Potential solutions:
1) Borrow, rent or second-hand a camera while you take a course or some workshops. For example, by the end of it of Photo I at college, I had have a much better idea of what I wanted.
2) Just buy a mainstream, well-regarded camera and a kit or prime and learn the basics yourself. But seriously don't buy anything niche or hyper-expensive yet.
(edit) I could care less which brand/system is 'better' but once you're invested, you're invested. *shrug* 'cept if you're really (choose 2 of the following) rich, hardcore or professional, then you might have a few systems.
