I wasn't talking about vulnerabilities, I was talking about products. Photoshop sets the standard for photo manipulation, Acrobat Reader is a popular .PDF viewer but it's also poorly coded from a resource stand point. There are some really streamlined open source .PDF readers out there that can load a big .PDF in half the time and consuming half the resources that Reader (note: opinion, not actually tested).
Flash is just one big bundle of poorly coded software that interacts with your system on some dangerous (i.e. exploitable) levels and even then the sheer number of problems it has is ridiculous. There's a reason that flash comes out with updates seemingly every other week while your web browser or what not does not.
(Actual count: Between Flash 10 and 11 there were 17 patches over 16 months...)

Javascript is another culprit and could find itself on the chopping block if something solid comes along.
