I really doubt Canon won't take the advantage of a firmware update to try to market it as an AF improvement and then leave it as an unquantifiable statement about improved AF.
It is funny how many people knew this would be a stinker before it saw the inside of a showroom. 1st gen is not an excuse - I would have fired the people who let a subpar product see light of day. We are too kind to these people and show way too much loyalty.
I have been on the sidelines with my Rebel Xsi because I am a casual photographer and don't need this equipment to earn my living. I will continue to wait one more cycle to see if Canon can fix AF issues with the Rebel, M series or the 6D and not keep making silly mistakes (one point AF on 6D) - if the next product does not deliver then I guess Sony or Nikon will be getting my money.
Windows Vista? (contrast win7pro)
Pretty much any 1st gen system or serious overhaul to a previous system.
All had serious flaws that is caused by 1st gen syndrome, compare 2nd gen products to these and its obvious of they're flaws. I never adopt 1st gen products.
