I'm new to the Mac. I bought one so that I could learn to program on it. I was wondering if people could say what third party software they feel is missing from the Mac? I'm not talking about little hacks to make windows turn blue, or something like that. I'm talking about useful applications that you would spend at least $20 (or more) on, which is either not on the Mac, or not to the quality that you require. Thank you.
