The 360 is NOT a well built piece of kit, it's probably the shoddiest electrical hardware item to ever be released to the mass market...
And the warranty repair costs of 1.5BILLION to Microsoft proves this fact...
How do you say it ? Someone at Microsoft beeped up BIG TIME
The 360 had one major fault, which is rectified by the manufacturer FOC.
Other than that, it is very reliable. I've had 2 360s now, for a total of 3 years, neither have ever broken.
So no, it isn't "the shoddiest electrical hardware item to ever be released"
