I just picked it up and in my honest opinion, no.
The only thing I can really find that someone might want that Photoshop.com Mobile doesn't have is text bubbles and the little frames that Photogene has. I just deleted Photogene from my iPod Touch a few minutes ago because of this. Plus you can make a Photoshop.com account and upload pictures.
