Touch wood, I've only had one console break on me, and that was the Wii. We all know about the ring of death, and although I've not experienced it, I did have to get the replacement power pack for the XBox. Going solely on personal experience, I've found Sony to be the most reliable; I still have my Playstation, going on 15 years old now, my ten-year-old PS2 and my two-year-old PS3. The latter is used more than any gadget in the house, barring my laptop, as I use it as a media centre. So far it's going strong.
