I'd like to add that Photoshop Elements is probably fine for the average user / developer that deals with graphics and that costs only around 60 Euros (Mac AppStore). And with all the guides, filters etc... around for Photoshop and the guaranteed compatibility with PSD files, it's a very interesting deal.
Yep. It's great for basic tasks. I used it early on when moving from Photoshop to Gimp... useful for dealing with files from new versions of Photoshop, but disabled enough by its lack of advanced features with layers.
