Hi, so I am thinking to buy photoshop elements to my gf for her birthday. She likes digital photography and she's pretty good at it for an amateur. Right now she uses some software that came with her camera, and she has a PC, not a mac. So I have a few questions: 1. Will the photoshop elements be useful for her? 2. Will it be substantial upgrade from that software that came with the camera? 3. Shall I go for the latest version? I've heard it is slower the the previous one. Thanks.
