Have to be fair, as un-microsoft as I am, during their crusade for world power, they did take over an outstanding firm that made mice devices for them.
They used to have a wired <$10 optical mouse that was a classic - now it seems some other company are selling the exact mouse with a different logo. Kensington or some1.
Also their Intellipoint Trackball Explorer was the best trackball ever - and vanished.
C'mon microsoft, flex it.
