Which is better: the Marble Man or the M570?
I have both and have mentioned them frequently.
The Marble (wired USB) was by go-to in the office. At the time, I scrolled less -- used the keyboard to flip slides, pages, etc. -- and had the work-issued wireless mouse for scrolling work. The Logitec software also had a crude scrolling workaround using one of the extra buttons.
The M570 stayed at home for the family PC. I occasionally used it on the rare day I did WFH.
Then pandemic. The M570 became priceless, especially having a scroll wheel. I've been doing a lot of work in Visio this year, and the crude Marble attempt just doesn't work; I need zoom (CTRL-scroll) and pan (SHIFT-scroll) more than I need vertical. And with a KVM switch to share it with the home PC, I'm set.
I was picking up some stuff at the office earlier this month and thought about grabbing the Marble just for kicks, but I left it there. (No one's gonna' touch my desk anyway.)
What would YOU do in this situation? Ever had to choose?
