There’s a high likelihood that you still have an old USB relic rattling around in a drawer somewhere in the house. It could be that flash drive you’ve not touched in years, not even for reinstalling Windows, or the SD card reader you have no use for anymore, or even the USB coffee warmer that you used a few times and got tired of. Many USB-powered devices, whether functional or recreational, used to add a bit of flair and whimsy to the PC experience, but ever since some of them were made obsolete, things haven’t been the same. I put together a list of five USB devices that I fondly remember, and I wish they would somehow re-enter the zeitgeist.
