Not at all impressive, but to maximize interactions on a newborn thread:
It's probably my PS3, which I would have gotten Christmas 2008 (or maybe it was 2009?). I recently started sailining the seas, and the most convenient way to watch those videos is to burn them to a disk, and so the PS3 is really just a glorified DVD player (can't even be bothered to use it's blue ray functionality)
Hey, keeping a first gen PS3 running after all those years is more impressive than you might think. Wayyy too many of those cooked themselves on 12+ hr gaming sessions back in the day
Similarly, my PS2 which I got for Christmas in 2003 is still running strong, I replayed Simpsons Hit & Run recently and it the console plays as well as it did when I first booted up.
It also has the honour of being the last device I own capable of playing DVDs since my PC's optical disc drive died.
