Auhim on 24 July 2008
Ouch. My first 360 lasted less than 24 hours (just wouldn't boot, no RRoD or other lights), so I just got it replaced at the store. I didn't want to get a refurbished (used, broken, then fixed) unit after using my brand new system for less than a day. My replacement system has been fine since then, but I've only owned it for a few months now.
My launch Wii got replaced in February 2007 due to an overheating GPU. I noticed some random artifacting (speckles/spots) on the screen whenever it was doing any 3D work and called up Nintendo for a replacement. I've never had any other systems break on me.
