Even as someone who has disliked MS since the mid-90s, I am willing to admit they have made some good products. The Intellimouse 2.0 was one of the best mice I've ever used. It was my main mouse for something like a decade, and even now, almost 25 years later, it still works as a backup mouse when I need it for something in my homelab.
People won't believe me that windows is an absoloute dumpster fire, sure it works most of the time but when it doesn't it quickly becomes apparent how much the whole thing is creaking edifice built atop pretty much every past version of itself. I could do a whole rant.
Excel is a very nice product, and I really enjoy AoE2. Even if it now has a quite large tech debt with HD the release version was super stable and a leap forward compared to its contemporaries.
One Note. I have yet to see anything from anyone come close. Works with all of my devices, allows me to use a stylus for designs on an infinite graph paper canvas, and damned good at note taking.
