My old pet peeve was waiting in lines and/or traffic.
My new pet peeve is Android Market games that use the name of a highly successful game in order to attract attention to an app that is a piece of crap. Today I saw Civilization and Pitfall, among others, and my intuition tells me that 3 seconds of my time is too high a cost for these.
This all made me wonder... Apple could, as a strategy, as dishonest as it may be, hire these people to pollute the Android Market with this waste in a solid effort to discredit its usefulness. I don't honestly think that's happening, but I do believe these people do the latter. There really needs to be a way to block certain developers so that I don't have to see their junk on my Android.
