I got some great images with my A70, as long as it was in a totally controlled environment and I could make about 20 attempts. Snapshots, of course, were all fine. The deal-breaker for me ultimately was shutter lag: I'd press the shutter release, the camera would think about focus and exposure for a while ... then a while longer...then go out for coffee, read a magazine, think a bit more, then make the exposure. Just forget about taking images of anything at all dynamic under slightly marginal conditions, and you are fine. Almost as important was its frequent failure to focus correctly at very close range, and its propensity to overexpose close range flash images.
I'm not decrying the A70 really. It is a great little camera in its class, but there were things it just could not do that an SLR does easily: responsiveness, focus, exposure, lens choice, etc. and they frustrated me no end.
