What apps/programs should I get

I've figured out how to pirate stuff for a while now, but it only recently came to mind that I could get premium versions or paid programs for stuff that I've been avoiding for years.

For instance, Google docs is the only (good) free doc editor app, but now that I can, I am trying out several normally paid apps.

Does anyone have any interesting suggestions for apps (or computer programs for linux and windows) that I could download now that I have realized the power I wield?
