Every one of them. I never had a console, including any handheld, permantly break on me. And even then the only console that ever broke at all was my PS3 (YLoD due to overheating), which I fixed easily.
I never understand how a lot of you always break their systems. These things don't just die on their own, seems to me, so it must be you guys! 
I still have consoles from 1977 that work perfectly fine to this day without having needed any kind of maintenance whatsoever for the last 40 years.
Though I did once get a second G7000 just to take it and my original one apart to swap around some components. I took the best and cleanest controllers (are hardwired), best performing video chip (strangely had noticable differences in image quality between systems), nicest looking case, you name it, to make myself an "ultimate" version so to speak. The one with all the "bad" parts also still functions properly
