Mouse or trackpad? Laptop or desktop?
#1: Mouse, desktop. I have a laptop but I mostly only use it for meetings that require I have computer access, which is pretty rare. When I was on leave it was my main computer at work, but I had it hooked up to two big monitors. I guess I do have a fancy mouse at home (Evoluent Vertical Mouse 3– not sponsored) to help combat RSI, though the only thing special about my work mouse is that it has a cord. I carry a mouse with my laptop as well because it’s so much less of a hassle than the trackpad or nub.
#2: laptop at home, desktop at work. Nothing fancy or special.
