LowriderS10, please know that I am not singling you out. I've seen this dozens of times, from lots of members. Your post just happened to be there when I saw it one time too many.
I bought a 5D because I wanted one. What is wrong with that? This "you're not ready to upgrade" attitude is prevalent on POTN. The general question is always along the lines of, "What is crop not doing for you?" or "What do you shoot?" That just seems a tad elitist to me. This may be a surprise, but most people buy a camera to make photographs. Of course, knowledge, dedication and skill levels vary, but owning a full-frame digital camera is NOT something one must prepare for. Buy it. Learn it. Use it. There is no magical blend of experience and wisdom one must attain before purchasing any particular camera. Why would anyone else care if someone's first camera, or next upgrade, is an A series P&S or a 5D3, or a 1DX for that matter? The only photograph I've ever won an award for was taken with a Panasonic DMC-FZ8. I take pictures of my cats with a 5D. On both counts, so what?
I agree with some of this and disagree with other parts.
First off, buy whatever you want, it's a free country. That said, there are certain cameras suited for certain ways of shooting, though you can certainly shoot anything with any camera. For example, if the op said they like to shoot sports cars in the rain, then the 5D classic and MK II would be a horrible choice, and a 1D series is really what would suit the situation best. Not that you couldn't shoot it with an XTi, just making a point. If the op shoots portraits in tight spaces with low light, a full frame camera would have a distinct advantage over a crop.
I don't think you must necessarily "prepare" for shooting full frame, but an owner of a rebel with all EFS lenses should know its going to be expensive and all of their lenses must be replaced also. DOF control on full frame is a bit more finicky than on crops since its thinner on FF for a given situation. Your thought of buy it, learn it, use it is certainly true, but many of the cheaper/used full frame cameras (5Ds especially), while excellent cameras, are not well suited to every situation.
Cameras are just tools, certain better than others for specific jobs, but all would get the job done one way or another. I currently own one of each Canon sensor size (60D, 1D3, & 5D3), and each one had its merits and drawbacks
