If we were to consider software failures as component failures, this poll would be a non-starter. Software fails daily. Got a 404 lately? Fail. Had to reboot your windows box? Fail. Got the latest "Here you go" or the PDF-exploit worm? Fail. Your spam filter did not catch all of your spam? Fail. Your fancy smartphone froze up and had to be power-cycled? Fail.
Half the software I use does not perform anywhere close to my expectations. I am used to it; I am a software engineer by trade, I write my own bugs, my expectations are remarkably low. As long as I can get by somehow without throwing my computer out the window, I consider it a good day.
