We need more professional software for Linux. I can't switch my work PC because Autodesk, Bentley and Dassault products to name a few. Personal machines that just run Firefox and things like handbrake or VM stuff, linux works great.
Professional apps definitely need work... as I mention, would be nice if a few would at least put a little effort into WINE testing and/or support in order to broaden use. Not even fully porting to Linux. This won't work for all apps, but so many have what are likely minor changes to get compatibility up.
