I acknowledge that they offered to fix the problem if it exists. But its obvious why one does not want their 'brand new camera' fixed. And they will have to convince any buyers down the road of their reason. But its a cop out by Canon. This is a design flaw, they should have replaced every single affected camera, or given users some kind of rebate for continuing to own a 'defective product'. I have a better word that describes this: "kyosei". (Japanese for F%$# every last cent from your most loyal customers).
seriously, get a grip. This is in no way a cop-out, do you have any idea what this fix will cost Canon? Do you have any idea what it means to be an early adopter? yes, you get to play with the newest, shiniest toys but you also have to deal with the potential design quirks that are still being ironed out and limited compatibility until other manufacturers/developers catch up and integrate. This is the same reason I don't buy a car the first year it comes out; they always have small glitches to iron out, buying one used is not too big of a deal, provided the owner took them in for all the required work. As an engineer that designs products, I can attest to the fact that no amount of testing will provide a perfect product; there will always be some odd ball situation that someone will come up with (Like shooting with the lens cap on) and complain about it. I've had a user complain that my product doesn't work if you unplug it. well, guess what? neither does your tv, toaster, microwave, etc..
If I buy a piece of electronics and they come out with a new board revision for a component inside of it, they're not going to offer you the new version if there's nothing wrong. At best, you can get yours modified. The only real way you will get a replacement is if it is a safety hazard (exploding batteries, under rated power supplies, etc)
So let's pose this question: what do YOU want Canon to do? replace your camera? refund your money? write you a check for the $200 you probably won't lose?
Guess what, it probably costs canon more money to apply this fix than you could potentially lose on resale. I think Canon has done more than enough and has earned more respect from me due to the incident.
in summary: you're an early adopter who is unhappy that you found out what it means to be an early adopter. Great, get your camera fixed and it will be indistinguishable to a serial 3+ camera, then use it. if you're worried about resale, go get a niche camera that depreciates slower (Leica, medium format, etc...)
