Manual focus. why the obsession?

I am wondering why too.  My experience with manual focussing cameras stretches from the 1960's to 2004 - owned all manual focusing rangefinders and SLR's with the exception of a single Ricoh GR10.  Got to be pretty good at scale focussing too, ie estimating distance and setting it on the lens distance scale.  With the X-E1, I'd rather stick to using AF with Fuji X lenses, than using legacy lenses and MF.
