I can't say I've ever broken anything, but I did once take the Rogue Squadron disk out of my Gamecube and chucked that across the room. It was that final Deathstar level that did it. I had just taken down two Star Destroyers and a piece of TIE Fighter shrapnel clipped me. I died just moments before the end of the stage and I cracked (luckily, the disk didn't!)
I am definitely getting less patient in my old age. I do tend to swear at the TV a bit when I get frustrated. All the examples listed so far are pretty much exactly the games that made me swear: MKWii, The Force Unleashed, SF4 - all cheap and nasty. I do find it is Japanese games that wind me up the most. Especially 3rd person games. They seem to take joy in knocking the player on their ass and taking away control. It is so frustrating. New Super Mario Bros Wii made me swear too. There are a few stages where enemies drop on your head - only you can't see then coming. It is totally unfair and cheap.
