I have owned 4 Xbox 360's and none were from failure.
1) Xbox 360 Pro had for a month and exchanged it for Xbox 360 Elite
2) Xbox 360 Elite had for 2 months and traded it in for a used 60GB PS3
3) Exchanged my used 60GB PS3 for a Xbox 360 Elite
4) Traded in my Xbox 360 Elite for a new 80GB PS3 Motorstorm bundle
My last 360 and the one I currently own was a year or 2 years ago when I purchased the Xbox 360 Arcade for $250. It has been running ever since. This 360 has the Falcon chipset also so its certainly reliable!
I did a lot of trading and exchanging but at that time I was confused on whether to own a PS3 or a 360 and ended up buying both and buying a Wii!
