Amen.
Mice with balls in them. Oh how I loved to clean them out every five minutes.![]()
We're still using them at work.
All our computers are about 15 years old with the exception of one Ipad. They only upgraded the memory from 128MB a couple of years ago. With the plethora of stuff autoloaded, they're using ~250MB just sitting at the desktop doing nothing. It could take over 30s to get the Windows calculator up. I've no idea what's in the network server, but judging by performance I think it's a couple of Zilog Z80s. Everything falls over frequently and simply entering a couple of numbers into the simple accounting system (it's a cash business, so figures have to be entered manually) can easily take >10mins. The data entry itself takes about 15 seconds of that. The rest is waiting while logging in and loading the software.
Ball and roller mice are a minor bother in comparison.
