There are many areas of IT where FLOSS competes very well. As well as the obvious success of GNU/Linux on servers (at factory and on the web) and Android/Linux on smart thingies (3.7M over Christmas and 850K per day average) there is a lot to be proud about on the desktop front. Check out Distrowatch‘s Hits Per Day for the last 7 days:
Not only are there 12 distros getting 1K+ hits per day but in a year that represents millions of potential converts to GNU/Linux. I know some shop for distros and others compare distros so the number may be inflated but it’s still an indicator of huge growth and wide interest. It’s not as large as that other OS or Android/Linux but there is a lot of interest in GNU/Linux nevertheless.
According to some research I have done there are about 150 million more PCs each year so a few million of those getting GNU/Linux maintains the share and may grow it. The visitors to Distrowatch are likely the ones who install their own OS. That leaves millions who also buy PCs with GNU/Linux installed at the factory.
So, growth continues.
