The real question is, "Does it matter".
None of us were happy when it took a dSLR 0.2 seconds to autofocus (despite the fact that we were perfectly happy focussing manually or using a rangefinder that took 1 - 2 seconds).
I think that, as in so many aspects of photography nowadays, we have to take a reality check and wonder whether the differences between cameras, lenses, etc., etc. actually impact upon our ability to take stunning photographs.
