K10D still going strong (flickr stats)

dpreview contracts spaces, making a mockery of my attempts to make a table, so let me just say that according to flickr, in terms of the number of flickr members and the daily activity, the K-x, K10D and K20D are in a three way tie for first place for Pentax dSLRS. The K-7 lags about 30% behind and although that gap was closing the K-5 announcement looks to have capped it's recent gains.

The K10D has been out 4 years, the K20D 2 years, and the K-7 and K-x about 1 year.

I suppose you can spin the story various ways, but what struck me was how many people are still actively using the four year old K10D. (I'm one, but I always assumed myself to belong to a small minority.)

K10D users: why haven't you upgraded?

(my reason: not convinced by the color rendition of CMOS sensors)
