See how dangerous that is? The long version of your comment is all part of what I'm calling "shopping." You're making your analysis of camera technology into your hobby, and making it into the focus of your expertise. I eventually did the same (the worst "shoppers" become "reviewers") but that's not photography. It's photo-tech. It's true that I wanted to be a writer more than I wanted to be a photographer, and today I am a writer of sorts, so maybe I should let myself off the hook. But I'm suggesting that, assuming I wanted to be a photographer, I would have been better off concentrating on taking pictures and making prints rather than becoming an opinion-expert on imaging technology and the camera industry.
What I said, what I'm saying, very deliberately, is that I'd buy two T3i's (or whatever) and forget about camera technology for five years. I'd be fine in those five years. I'd get to shop again, and when that time came I'd know I could wallow in photo-tech all I wanted. Until then, you should use what you bought.
And, incidentally, I'm speaking from actual experience. I tend to be obsessive, especially under stress, and I did make my living for a lot of years writing for magazines, which meant I had to keep current with photo-tech issues. Right after my son was born, I was the single parent of an infant, had moved to a new city, didn't have a job, didn't have many friends, was suffering serious sleep deprivation, serious money worries, etc., etc. Talk about stress. I found my obsessiveness getting out of control. So, as a "cure," I chose one camera, two lenses, and one film, and decided, willfully, to "stop shopping" for three years. The "three years" ended up lasting for four and a half, and I did some of my best work in that four-and-a-half-year period...and was the happiest I've ever been with my photography avocation. So I'm not making that advice lightly; it's something I've actually lived.
In forty-five years of film cameras, for personal use, I owned three cameras and bought lots of film. In ten years of digital I have owned five cameras and bought no film, just computers, software and printers. So tell me again about saving money by going to digital?
