If you are a Windows developer, you will surely have heard Microsoft's new pitch: build Universal apps. The idea is that you can run your apps on any of the company's platforms with changes needed only to the UI, not to the underlying code base. But, if you are a Windows RT user, Universal apps signal the end of the road for your device.
Microsoft has said that after Update 3 is delivered to Windows RT users (primarily Surface 2 owners), the device will not support Universal apps. This means that if a developer takes advantage of the new functionality that the company is pushing heavily, that developer's app will not work on the company's aging tablet.
