[Prize Draw] Let us know about your favourite bit of tech

What classic device would you like to see updated (if technology issues were no problem)?

I wish they still made mp3 players with hundreds of gigabytes of storage and batteries that lasted for weeks. Does anyone else remember the days when things didn't have to be constantly updated, plugged in and subject to subscription charges? And let's not forget the ability to actually own the music and audio books you had paid for and bring them anywhere, without suddenly losing access subject to the whims of big tech companies. Bring back the mp3 player!
