Thanks, the scroll wheel is a good reason, but I don't find the others compelling. > It required a special port which couldn't be used for anything else, taking up extra space and making plugging your device in less convenient. I don't find that a negative, the mouse is always connected and I've never once thought "I wish I could unplug the mouse so I can plug in the printer and charge my phone". > It's so convenient by comparison to be able to plug a keyboard or mouse into whichever USB port is easiest and have it just work without special drivers. For most people with a standard mouse and keyboard this was never an issue (except for the scroll wheel one you mentioned). For non-standard ones, it still has to install a driver doesn't it? I thought windows just installed it transparently.
