Maybe the Minolta x700 would be the steam engine. Not the 7D.
I don't see any reason why the 7D couldn't be an every day camera: her controls and handling are still the best you can find, she is quite light, AF is fast and reliable enough for everyday subjects, you can print 8x10 or even 13x18 if the photo is technically super good. Hell, with some postprocessing and upscaling in topaz GP, I could print 20x30 and no one could tell.
Her only "downsides" are 6MP, no crop, a DR a bit low forcing you to expose correctly, and slow frame rate.
And of course the fact she's an old camera and eventually will die sooner or later.
Keep everything as is in the 7D, and just swap the 6Mp sensor for a 12 or 16Mp sensor with 5fps. I'd buy such a camera. (No the sony a700 and other in this lineup don't do that, close but not close enough)
I shoot landscape, closeup, abstract, street, architecture, macro: not everyday, but at least once a week with the 7D. And absolutely no one can tell what print was shot with her or any other camera.
I don't shoot wildlife with the 7D only because my white 400mm is dead for years and I never replaced it.
