I know I'm late to the party, but thanks for posting your humorous story Papillon, very entertaining read, glad to hear that you're liking the K-01.
Just as I enjoy Marmite, I like the K-01. First I bought a Yellow one from the US which came fitted with a folding screen hood, and really liked its simplicity and of course the design. I knew the sensor was very capable because I was using a K-5. Then I noticed a black one going very cheap in Ireland with the XS 40 so bagged it. An interest in full spectrum photography spurned me on to splash out on a converted white K-01 - IR is lots of fun. Finally, to complete the set I snatched up a very inexpensive silver one. Of course you geeks will have noticed that four is not the complete set, as indeed did I. The Smurf was not imported to the UK, but I did come across one on Ebay (mode dial top missing) and when the price fell to the correct level, I scooped it up (mode dial now on order).
Only a few people will really understand my curious behaviour - surely one is enough! Yes indeed, just one in each of the five colours, that's one for each DA limited lens.
I also use them to park DA* lenses on so that capacitors are kept charged. Now I have been told that this is nonsense, but hey, none of my old * DA lenses (7) has suffered from SDM failure so I'll stick to the superstition and every few days press the shutter, do a little fiddling with focus, and keep my fingers crossed. It tells the lenses that I care for them, and they reciprocate by performing perfectly.
Back on the K-01, I do wish that Pentax would bring out an updated version with EVF and maybe the FF sensor. Same styling by Marc Newson, but slimmer body (grip apart) and an 'aperture ring' to maintain flange distance and free up the rear dial for shutter speed or +/- exposure. I do agree that other features like improved focus speed, full HD video, etc as suggested above would make it a nice camera.
But please, Ricoh/Pentax, just in one colour!
