I preordered mine on the announcement day and received it on March 26. Yes, I still remember the date it arrived and I took that day off to test it out. Then came the light leak "issue", followed by insane price drops just 5 months later. I'd be lying if it didn't bother me at all.
But we can't say right or wrong about the decision made in the past based on today's situation. That "if I had known..." scenario never exists. In my personal situation, I needed it because my 20D had 80,000 clicks and was near death. I was waiting for the 5d3 for quite a while. The 61 points AF system immediately grabbed me ( the reason I passed 5D2 was mainly because of its not so great AF performance and my wife gave me a firm "No" to 7D because she knew I would get a full frame sooner or later). Am I happy with the camera? Absolutely. I've been using it a few times a week and have shot thousands of memorable photos of my two little girls. So I paid extra price for the priceless moments of my family. From this point of view, it worths every penny!
Happy shooting, folks. Forget about how much you paid for it. The more pictures you take, the more values you get out of it.
