Mice were available, just not generally that useful because so few applications supported them. Usually they came with a bundled paint-type program. IIRC, in the early days of Windows (i.e. 1980's probably into the early 90's) they sold bundles with mice since they were still quite rare for people to have on PCs. They were just another input peripheral you could buy like joysticks and digitizers. Getting software to work with them was another story...
