Mine… My Xbox 360 slim only costed 129 euro back in 2012 and to this day still work like brand new, you would think that the disc drive would stop working but no. Never had the need of open it or clean it’s insides. Still great, I just don’t use it anymore since I feel it’s outdated and loading speeds are better nowadays.
Roku started off selling a series of little boxes with HDMI ports (or little sticks that plug into an HDMI port on a TV) to to make any HDMI monitor a “smart TV.” Hardware-wise it’s not dissimilar to a Raspberry Pi, it’s a little ARM chip made by Broadcom running Linux with a smart TV GUI running on it. Nowadays TV manufacturers build in a little ARM computer into the television itself and partner with Roku, or Google, or maybe one or two others, to do the UI and such.
