habit and practice. op himself said he believes gimp can do wonders, but he's migrating from adobe and is accustomed to photoshop's shortcuts, ui and workflow.
imho, people go wrong expecting same experience in different application. yes, gimp works very differently but when migrating, one should count on different ui and logic. afterall, ps also have learning curve in the start and none complains.
it's similar to users migrating from windows to linux, expecting same windows ui and workflow, blaming linux bad.
