Getting friendly name for SharePoint 2010 version

Typical question for people working with SharePoint – what version do they have? Then you get a bunch of numbers. Those days are over for me. I have wrote this class to finally get quick and clear answer from the client.

Versions are hardcoded so they need to be updated from time to time but in my case that is ok, as the client updates our product quite often. If you don’t have this scenario, well you could create some REST service for it.
