Few guys I know use this... havnt used it myself (much) but I figured you photoshop fanatics might dig it (and its LEGALY FREE ) http://www.gimp.org/
Hahaha! Good point... But still, might check it out if you have the time. Its pretty powerful for the price!
I just like to play around once in a while so I use the GIMP. Can't compare it to PS though, never used it.
There is actualy a skin somewhere out there that makes it look much alike to that of photoshop. Think it was called "Gimpshop" or something like that.
