I'm considering very seriously upgrading my "daguerreotype apparatus"

and I'm interested in the new Pentax K-X.
I'm already aware of the tech. specifications and have been perusing through dpreview foruns so I can get a few feedback, but the brand loyalty around there is a very serious business, so I was hoping anyone here shoots Pentax, specifically the digital K-M or even the new K-X, and tell about th pros and cons from a "biased" day-to-day user perspective
Thanks in advance!
