Originally posted by creampuff Sony A-700 owners have been plagued by their cameras hanging/freezing, requiring a hard reset. Or how about Nikon D300s that AF intermittently or won't AF at all, or for that matter the pretty poor battery performance. The 40D may have a bigger LCD but it is so-so resolution wise and Live View implementation is nothing to shout about.
Don't forget the AF problems with the Canon EOS-1D MkIII, and the weird image capture problems that D3 users had to deal with, and the dead battery syndrome that users have reported with the D300.

Except for the hot-pixel issue, that Pentax has addressed with a firmware update.
Most of this just goes to show that almost any sufficiently intricate and complex product may have a bug or two to work out. I certainly wouldn't have a problem buying a K20D, except I can't afford one. If I had all the lenses I wanted(about three more than I currently have, perpetually), I would buy a K20D. The expanded ISO range is nice, EDR feature would be nice when I wanted it, don't care much about live view (it may actually be an offense against nature), 3fps is fine for me, I don't need my DSLR to fire at the rate of machine gun, although I know some people do need more than 3fps.
That said, I can't say I'm rushing to dump my current DLSR kit (K10D/K100D/*istDS) so I can replace it all with a K20D. I have to say the K10D may have been almost too good, and it is too bad it had to be replaced due to marketing concerns. The fact is that if Pentax hadn't replaced the K10D, they would have started facing criticism from lots of sources about the "old" "outdated" K10D. (Point of argument, PopPhoto lauded the Nikon D40, but only a few months later, bemoaned that the 6MP sensor in the K100D Super was paltry compared to other models on the market. Feh! I know I personally don't get too concerned with what PopPhoto says, if you read carefully and compare to the lab results you often find discrepancies, but there are people who read PopPhoto and take it as the TRUTH of all things) Whether the criticism would have been valid doesn't matter(despite the fact that Canon JUST upgraded their mid-range model to 10MP from 8MP near the end of 2007.)
So the K10D had to be replaced for competitive reasons, but that doesn't mean I have to replace my K10D, I'm still happy with it. I wouldn't mind adding a K20D, maybe, but like I said, as a hobbyist, I can't really justify it, I mean I hardly push the K10D to it's limits. Having said all that, the last time I found a new K10D body, it was only about $100 less than the K20D, and that makes the K20D look pretty nice. It also means that my K10D has appreciated, since used bodies go for more now as well.
