Having worked for the federal government, let me assure you, Windows 7 will be around for a long time. But let me give a better example: Samsung mobile devices.

Having worked for the federal government, let me assure you, Windows 7 will be around for a long time. But let me give a better example: Samsung mobile devices. Since Samsung was so clever in naming their default browser "The Internet", there are a metric ton of folks who will be using that browser on their Galaxy S5s for a few more years. I think many underestimate those two groups, the ones that won't upgrade due to simply misunderstanding the whole mechanism, and the ones that are locked in by government infrastructure.
