I have two worth mentioning...

My Microsoft Sidewinder Mouse. The thing is still working like it's new (4 years later).

And an old 17" TFT LG monitor. It's stylish, the base folds in for easy transport, and still works like it's new. (6 years later). Oh how I wish LG still made monitors that great.

Oh, and my Hitex NES console. Dunno when it was made, but grew up with it, and it still works.
