How would you change Pentax's K-7 DSLR?

Pentax may not be the first name you think of when scouting a new DSLR, but it's certainly closer to the top now than it was prior to the K-7's release. The semi-pro cam saw positive review after positive review flow in, giving even the Nikon and Canon faithful reason to pay attention. At right under $1,300 for just the body it didn't come cheap, though the high-def movie capture mode, ability to snap HDR shots natively and 14.6 megapixel sensor help to justify the MSRP somewhat. What we're really after here are your thoughts; for those that bought in, have you been pleased? Is the low-light performance sufficient? Is the autofocus snappy enough for your tastes? Or more importantly, how happy are your clients with the results? Comments are all yours, so get to it!
