I was surprised by Microsoft. I could see IT department heads missing Microsoft and XBox loyalists, but other than that, who would miss Microsoft? Did they survey a lot of people in Seattle?
The gaming community would loose an awful lot too. Not just PC Gamers, but most of the industry development tools and workflow are largely Windows-centric.
I'm sure a ton of games would be upset as well. The Steam hardware survey reports that a 96.6% of users are on some version of Windows.
