I know Sony products are failure-prone, but I've never had a problem. Hell, all my consoles still work perfectly, regardless of how old they are or who made them.
My launch PS2 is still working just fine, plays CD and DVD games like a charm. I even flip-top modded the fucker and it's still chugging along without a hitch.
I've never had a single problem with my PS3. The Sixaxis controller batteries last forever, I've never had Bluetooth synch problems, the Blu Ray playback is fantastic (can't speak for DVD playback, as I use my upconverting DVD player for them), and while the online features do pale in comparison to XBL, it's free, so I can't really complain.
