Con Latest versions of Photoshop are subscription-only
While you can still buy CS6 from 2012 without needing a subscription by contacting Adobe support or the cut-down Photoshop Elements, any full-version version of Photoshop past CS6 requires a subscription.
The standalone version of Photoshop costs $19.99/month, though it can be leased as part of the Creative Cloud Photography bundle that includes Lightroom for $9.99/month.
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 No PC version
The PC version has not yet been released.
