Yep. So far so good!
If there are any issues I guess very minor.
1. I've seen it overexpose a few times, very rare though.
2. The LCD screen is too good! Is that a problem?
When I import my photos to my laptop, I am a little disappointed that the brightness/exposure of the photo is actually a notch lower. I have my laptop calibrated with Spyder 4 Express. Not sure if I am doing anything wrong.
3. I don't know if this is the same as other models as my K-x is now with my brother so I cannot confirm. But when you set an Exposure Compensation/Bias in another mode (e.g. Av), then you shoot at Manual mode. The Exif you get will have an Exposure Bias written on it. It is a very minor quirk I know, but it shouldn't have that info right?
