This brings something to mind... File sizes. Guess one reason I'd rather go PSP over PS [in multpass study modes... which get to 15+ layers...] is the file sizes. A saved 640x480 6 layer psp image comes in around 800k while a psd come in around 1.8mgs... zipped it comes in around 1.2mgs... still higher than the psp file. Just something that means disk space-study stuff for me... plus it takes longer for large layer studies to load in PS and the layer requester is not as easy to work with as PSP is. Still I'm glad I have PS. But than again... it's just a tool that has it's place.
