These should have been in the list. Foorbar, Picasa, AVG, and Miranda IM
As others have stated ... quite simply what the hell is ITunes doing in there remove it now!! Instead what about foobar2000 now that is excellent! it was a bit buggy when it was first released but its come along way since then and now i consider it the best music player/library tool out there.
Picasa for image viewing you can also sync your albums online for people to see.
And AVG, you have to have some sort of AV in the list this is the pick of the freebies to be honest.
I would also replace Pidgin with Miranda IM which is simple, clean and supports all the main social and IM networks such as Facebook, MSN, Skype, and Google Talk.
