Having used a 5D, 5DII, 5DIII, 40D and a 60D, I will say of those bodies the 60D was by a far margin, my least favorite and least used digital body ever.
My 60D is gone now and I wouldn't use one like it again, unless Canon (re) re-thought how the xxD series is made. For instance, the physical UI, firmware/hardware things like the lack of manual adjust for ultra-fast lenses, and that funky mini-grip that it has.
No one thing can be all things to all people, of course. But with Canon that seems to me more of an accounting and marketing challenge, than an engineering one. Canon can do many things in the engineering arena
