You'll never look back ! I just received mine a couple of days ago and i can't fault the camera in any way (for my needs at least), save perhaps for the battery life but i took approximately 650 pics with the first full charge, with heavy menu fiddling to get in touch with the new interface (which is fantastic btw, coming from a k200d). I suppose it's a good number compared to other cameras but i was used to the everlasting AA batteries in my k200d
The camera just feels "right" in my hands, everything is where it should be, operation of any kind of function and task is smooth, fast and quiet.
Image quality is superb...i mean this is not a special photo, but you can click, download full size and enlarge to 200%...you can see the fine textures on each little "branch", and it is an ISO400 shot developed from raw with no noise reduction applied !
Be sure to have some quality glass to truly exploit the full resolving power of this 24MP beast.
