I'm transitioning from PSP to Photoshop. I have PS 7 right now...but will be upgrading to CS5 soon. I'm a tagger by hobby, a photographer and digital editor by new trade, I guess you could say. I mainly wanted to swap because I want to be able to work with large files with out the lag I get from PSP. That and my husband is fed up with having to buy a new version every 6 months or so...lol.
