I only have the PSE
for Mac. It's a great piece of software. I like the precision editing and the ability to work with layers.
However, I have found that Aperture is really good, better actually, for enhancing the photo, to bring out the best in the shot. Aperture also does a good job of cataloguing the photos... and you also can get your shots on photo stream through the iCloud.
They both have their advantages.
The full PS
version? That, I don't know.
