My family's original Wii stopped reading disks after six or something years of use. Eventually we just sold it, and I let them have mine. That one still works perfectly, I was even playing Wheel of Fortune with them when I went home for the holidays.
Only other console I had issues with is my original 3DS model. There are thin lines on the top screen from closing it over the raised touch screen, the L-button doesn't work, and the control pad is worn down from playing Smash Bros. Fortunately all of my games that require L are Circle Pad Pro compatible, but the physical damage is more than a little annoying. If NX turns out to be a console I'll probably get the New 3DS, since I still have so many games to play on it.
