I decided to try out the in-camera editing on the CX1. Thanks to the high screen resolution it works pretty well and especially the level compensation is helpful to get more contrast in your images. The in-camera editing options also put a different spin to the phrase "Getting it right in-camera".
While it is better to use a computer and a decent program, it it nice to be able to adjust a few things quickly after taking or while reviewing the picture. The CX1 saves a copy with your changes so you won't lose the original image and can easily experiment a bit. It is a bit like drawing sketches so that you can get a quick idea about different ways to process your image.
