I should mention a more recent computer purchase that may turn out to be the best I’ve ever made.
Just got a Vertical Mouse last week because of the standard one causing me intense forearm pain while lifting weights. So far no sign of any pain and the increased functionality of four finger buttons, 3-buttons +scroll wheel, and the two thumb buttons is a nice improvement over my old standard 2-button +scroll wheel mouse. It’s taken some getting use to but now there is no way I will ever go back to a standard mouse.
