GNOME Co-Founder Still Uses Linux
Miguel de Icaza started the GNOME project back in 1997 along with Federico Mena. In recent years, my interactions with De Icaza have been all about Mono and his new startup Xamarin.
In a recent conversation I had with De Icaza, he told me that he was 'heartbroken' that his company is not focused on doing Linux desktop stuff. That said, he also noted that mobile developers are very pragmatic.
