Not all coders are technology nymphomaniacs. Some of us have actually found what works best for certain tasks, and stick with it. I've been using Qt in professional life for maybe 4-5 yrs now, never had to touch .net or microsoft stuff after Qt came out. It's very simple, choose the wrong toolkit, and you won't find any developers. (or the ones you find, you won't want) I'm certainly not ever going to code for .net, they had their chance to put Qt and blew it. It's extremely rude to force people to learn technologies that are INFERIOR.
