My launch PS3 died about 3 years in after heavy use. Had it repaired and was sent another launch 60GB that itself just died (UC3 killed it, didn't make it past the initial start screen
).
My launch 360 died about 1 year before the first PS3 after heavy use. Purchased a Falcon MOBO Elite and had the original replaced under warranty. Gave the original away, not sure about it's status. Elite just died on me after heavy usage up until about the last 3 months where it was barely used. Skyrim killed it, though, didn't even make it past the first loading screen to start the intro
.
I now have a PS3 Slim and a 360 Slim. And 2 consoles waiting for me to bother placing a repair ticket. I want my same PS3 back, though, because I hadn't done a full backup in over a month.
On a side note, comparing the various revisions, IMO, the PS3's feel of quality dropped off with each subsequent change, while the 360's improved. My 360 slim has a better quality look and feel about it compared to my launch and Elite. My PS3 feels more like a toy than a piece of A/V equipment like my original (not to mention the laughable USB port count and all the additional little hardware "nicities" that have been dropped off). Also, my PS3 Heavy had a much quieter BRD than my slim, from what I can tell, and I didn't have fan noise issues like other heavy owners have reported.
I do like the HDMI CEC support in the PS3 slim, and the better HDMI chipset in the slim 360 (since it can auto-switch inputs).
