I left my work mouse at the office yesterday and will be WFH most of this week, so once again I'm completely unironically using the IntelliMouse Optical USB and PS/2 Compatible for serious stuff.

It tracks slower than a modern optical, but that can be adjusted in software, and it's got more than enough buttons for what I need day-to-day.

Adopt, don't shop - there's a lovely senior mouse in an op shop near you that will give you boundless love, if only you'll give it a chance. #retrocomputing
