The verdict is in: EOS-M is terribly SLOW.

The EOS-M's auto focus speed is 2 years TOO LATE.

" Then, there are those that nearly drive us to tears, instantly tarnishing our opinion of otherwise capable models. We were devastated to see that the EOS M's focusing performance falls just shy of that latter grouping -- the cameras that just plain stink at bringing a subject into focus quickly."

"...but the dismal focusing performance means SLRs will probably be far more appealing to these users."

Sure it's just one review from a non-photography-specific site, but the long-suspicion of many (based on the youtube marketing hype) is now verified. This is certainly just a BEGINNING of many other reviews regarding its sluggish performance.

What a mess.
