not to threadjack, but I've always wondered just how much slower the 60D controller (no joystick) is than the 7D/5D joystick in real world use.  anyone here used both?

Forget the joystick - not in a good place while your face is planted to the back of the camera. Assign it to the quickdial adjacent to the shutter. Press the select button with your thumb and spin the dial to the point you want then shoot. I use it all the time for fast paced action.
That would work..but I'm usually using that to switch shutter speeds around in manual mode as I'm shooting...

I would work faster...but I am trying to learn to shoot in manual mode, and I'm always dialing in my shutter speed with that one...

There's plenty of advice on how to select your focus points already, so I'll pass on info as to why Focus & Recompose Sucks...

WOW!!!

Thank you, that really illustrates things!!  This may be why I've had so many soft shots starting off with my camera....I was thinking I sucked, or that maybe my lenses and camera were faulty...but this may explain a LOT.

Thank you,

those descriptions are not correct, they are overexagerating the effect unless they are refocusing on the other part. if you keep your technique good when you recompose the distance does not change THAT much

Applying some trigonometry, varying the angle, keeping distance to focus point the same, one gets the following:
Distance=8', angle=5 deg, the error is 0.3667"
Distance=8', angle=10 deg, the error is 1.481"
Distance=8', angle=15 deg, the error is 3.386"

So depending on DOF you may or may not notice too much of focus error...
