Con Batch editing of images is not straightforward
Photoshop is designed to work extensively on one image at a time and while batch editing support exists, it's not that intuitive to use.
Con Learning it can take some time
While you can relatively quickly learn how to perform a few basic image editing tasks, understanding Photoshop's ins and outs can be difficult. It's partially due to the sheer amount of functionality that Photoshop packs (and understanding that some of the advanced functionality can take a while to understand on its own), and partially due to it being aimed at professionals with little hand-holding for novice users.
Con Asset management capabilities are lacking
In Photoshop asset management is done through a separate program called Bridge. As Bridge is supposed to be a file management tool for not just Photoshop's files, but for files generated by all of Adobe's applications it covers a breadth of capabilities, but not depth.
Con Ancient interface
The interface looks and feels like it came out of a 20 year old commodore amiga.
