The author says it got better, but in reality Unity already overtook Windows' UI and it will overtake Apples UI with one of its next iterations.
As a younger (though not that young) developer I have to agree that using MS developer tools is the wrong way of doing things for most new software, not all of them though, it sure has its uses. But I am strongly against proprietary software that only runs on one OS as that will only lose you business. Even the game platform Steam seems to have gotten to that point, a Linux port is on its way.
