Yes, I do.
I'm in the process of looking for a birthday present for my Dad and the 860 is one of those that was on my shortlist. I have tested it a couple of times and I honestly cannot rate it. The IQ is mostly good - quite low noise until 800 ISO; the usual excellent Canon colour rendering, which is very natural and not over-saturated; very good detail (better in fact than most Panasonics with their Leica-lite lenses).
Now the poor bits. An awful menu system in comparison to Panasonic et al, which is very unintuitive and has no relation to the excellent Canon SLR menus; a flimsy battery cover, in which I don't have much faith (it will get used a lot for charging the battery and downloading images); it clips highlights a little too much and can under-expose in high contrast; and some reviews have noted that the finish is too easily scratched, though I can't comment about that, of course, having not attempted to prove it!
It's not the cheapest of its kind either. Hope that helps.
