So, the initial small but statistically relevant poll sample so far supports obvious observation on these forums to date.
A vast majority of those who actually own the 5D III love it, are wholeheartedly satisfied with it, and are not complaining, even or especially about the price.
And then there are those who would definitely like one but can not afford it at this time, or ever. This subset is divided into those who are hopeful and those who are bitter and thus complain.
And, of course, there are "other."
