I am certain that many people will still continue to run Win32 for years to come (I still know many people running Windows XP even though it is end of life 🙂 ).
Gartner predicts that by the year 2020, less than 10% of people will be on Win32 apps (WinNT) and they will be running the WinRT based apps running on Microsoft’s Metro interface. However their overall market share will decline.
I wonder though if this major technology shift will cause people to reconsider continuing with the Windows platform. Due to this major decision they need to make, why not go over to another platform or drop desktops completely… perhaps only use personal devices (smartphones, tablets, etc)?
Are you going to embrace Windows 8?
