The same can be said about the Xbox 360 and PS3. Why is it that Nintendo has a stupid 12 month warranty while Microsoft offers a 36 month warranty? The Wii is still as prone to failure as the 360 but since the 360 has been out for a year longer more people have found things wrong with the system.
I bet you all the contents of my wallet that by this summer there'll be a whole lot more people like me who have had the system break down on them.
I told myself never to buy a system at launch after the PS2 NOT READING BLUE BACK DISCS SRRY fiasco but when the only Wii in the entire county had a copy one month after the launch date I couldn't resist.
XBox 360 only has a 12 month warranty for most errors, too. The 36 month warranty is just for Red Ring of Death-related failures. And the 360 is way more prone to those particular breakdowns than either of the others--current estimates put it at about 1 in 3 of the early systems will break down, and 1 in 10 of the current board. But the suggestions I've heard suggest that the ones that are going to get RRoDs are going to do so in the first six months, so I doubt the extended warranty will make much of a difference anyway.
This is all based on reports that the various gaming sites have done, especially an
interview with a former MS employee who spilled the beans on the 360's Red Ring failures. There's little question that the 360's been suffering more breakdowns than the other systems. Microsoft has to have that extended warranty or no one would want to take the risk if they've got a one in ten chance of getting a defective system.
I'm not trying to say that it doesn't suck that your Wii broke down--any line is going to have flawed units come out, and you were pretty unlucky. But I haven't seen any information suggesting the Wii or the PS3 are as prone to failure as the 360.
And this isn't me speaking as a Nintendo fanboy--I just bought my own 360, and I'm keeping my fingers crossed (and the system as heavily ventilated as possible) that it doesn't break down. That's why I've got this information at hand--I've been trying to keep the information at hand so I know if I'm going to be throwing my money away or not.
