I have owned a PS3 since not long after launch (because: Gran Turismo), and also got a Wii a few years later, along with a Wii Fit.
The Wii Fit is a fancy bathroom scale with "games" that are actually somewhat aerobic and taxing, yet sedentary enough that you can play them in your apartment, along with fitness tracking
It's also an excellent emulator-box, once properly hacked, with good support for SMB network shares and local SD/USB storage of all common types. (It also makes a decent-enough Cinavia-ignorant DVD player, once hacked.)
I have an original NES and many of the games that I like, but I haven't plugged it in after any of the last few moves, because the Wii does it just fine and in such a way that Super Mario Brothers, with a borrowed ROM image (I also own an original copy) and a GPL'd emulator, matches my memories perfectly in terms of timing and gameplay. (I used to be able to, and still could if I tried, play the first parts of level 1-1 with an ear pressed against a loudspeaker directly connected to the audio jack on an original NES, with no video display.)
The Wii was the only broadly-hackable console of the last generation, and this was a huge factor in my decision to purchase it. It was also relatively cheap, and included a proper GameCube worth of accessory ports and native (NOT emulated) compatibility.
It's also the only gaming system I've ever been able to use in the past dozen years or so with my more-general friends: Anyone can have fun with Wii Bowling.
