We still use them. Laura has been bought a laptop by CFSN to use when off sick (like now) and prefers to use a mouse and mat as it's easier to control than the inbuilt mouse.
I use them in my mouse martial arts studio and wrestling/boxing ring, other then that they're fairly useless.
I've got a glass table But my mouse still works pretty well without a mat on my computer desk. Maybe I've set up my glass table wrong.
NO - Useless these days with optical mice. I've gota consignment of VHS librarycases in the form of fake books if you want as well.
I use one out of habit Mouse works just the same whether there is a mat or not but the mat at least keeps a mouse sized area of my desk free from paper and other clutter
Not me. There are loads kicking about at work collecting dust that have been given to us as freebies from suppliers.
