When I first started using PC compatibles in the early 1990s, Microsoft mice were recognized far and wide as the best mice around. I used their third model (I believe), which was a smooth, white rounded number with an incredible feel and response. I still use those mice on some of my older PCs. Although I've never used the mouse pictured here, but I'd wager that it was pretty good by 1983 standards.
I always found it ironic that Microsoft made some of the best mice on Earth, considering the sorry state of their software at times (I remember thinking this in the Windows 98/ME days — Microsoft's lowest point so far). Whomever is/was in charge of their hardware division really knows what they're doing, although I think they've been slipping up a tad recently by releasing keyboards with weird, nonstandard layouts and too many mouse models with superfluous buttons. But as long as they still sell this baby, (my current mouse of choice), I'll be happy.
