It is ridiculous the amount of money they charge.
Unfortunately it compares to Photoshop of around a decade ago. There are things happening in modern Photoshop using built in AI that users are not even aware of.
If you want to try a simply experiment do this. Find a photo of a person taken at high resolution open PS CS5 and zoom in to the mouth.
Do a simply trace around the inner lips so as to select the teeth and desaturate them to make them whiter, adjust the levels too and save. Zoom out and look how smooth the adjustments are and no visible edges.
Repeat on a duplicate photo in Pixelmator. The edge you traced will show up after the adjustments like a sore thumb and you will have to blur edges and fiddle around to hide the correction.
It is hundreds of tiny features that are automatic that make our work flow fast and easy these days compared to a decade ago that make PS what it is today.
BTW I am not saying Pixelmator isn't fabulous for low end users, it may well be but it cannot be compared to PS for serious work where time is money. The time PS saves pays for the extra in a day or so! Also I am no huge Adobe Fan either, I wish Apple had a PS rival and an iWeb Pro ... <sigh>.
