FUD Zilla cites numbers from a SquareTrade study about failure rates of the current generation of consoles. SquareTrade claims only 2.7 percent of Wii users reported a failure over the last two years. For comparison, about one in ten PS3 consoles failed and almost a quarter of all Xbox 360 consoles. However, the study also points out that Wii owners use their console about half as much as Xbox 360 or PS3 owners.
Basically, Nintendo's white toy is 9 times more reliable than Xbox 360, 4 times more than PS3. Over two years of use, just 2.7 percent of Wii users reported a failure. One in ten Playstation 3 users also saw their pricey toy expire, while Xbox 360 owners reported failures in 23.7 percent of all consoles sold.
The Wii's Achilles heel are its controllers and power supply system. The Xbox 360 and PS3 commonly face issues related to disc read errors and some output problems.
