Why PS3 and 360 drop dead for the same reasons

[Reasonable]

Pretty redundant. The core point mentioned holds true for most electronics.

I suspect PS3 does fail more than some imagine (certainly mine has!) but it seems unlikely to me that Sony would be able to dodge the trouble MS had if they were roughly equal in failure rate.

Clearly, the evidence suggests the PS3 remains much less susceptible to failure than the 360.
