Let the hive mind of Engadget get that for you.
"I just switched to Sprint from Verizon about three months ago for the Pre. Then I went for the Hero about a week ago. Now, I miss my hardware keyboard and am thinking about switching to the Moment. I am still able to switch back to Verizon if I want and get the Droid when it arrives. Should I just trade up to the Moment when it comes out, see if I like it, and if not switch to the Droid? Or something else entirely? Help!"
Pentax is a very well known brand in the photographers community. They dont have the same penetration that Nikon or Canon does but they certainly can compete spec for spec if not better. Pentax, from what i noticed produces a very nice set of optics for all their cameras. They pack in alot of features usually.
i have no personal bias towards Pentax either, I shoot Canon.
