Twitch: Not "as well." I think all Qs should have WR, which can only add to its appeal, differentiate it from any competition, aid in finding its market - and help justify its price. In fact, I think all of Pentax's mirrorless cameras going forward should have WR. There was talk for a while that Pentax might do this with all its DSLRs - a missed opportunity in my mind.
Ogl: You've read and agreed with my misgivings about the Q. I still have them. And while you may scoff at the idea of a 1/2.3 sensor being used for landscapes, that fact is you (and most likely me as well) won't be buying ANY camera with that kind of sensor. However, many mainstream consumers will and they will use those cameras the way we use DSLRs. I can see many hikers and backpackers being attracted to the concept of a tiny camera like the Q with WR. A much better option than the W-90, wouldn't you say? Yes, I know, the W-90 is a waterproof camera for underwater work. But many consumers buy it, and other cameras like it, for general outdoor use so they won't have to worry about damage from things like rain and dust - despite the compromises of folded optics and high ISO noise because the cameras lack true shake-reduction..
