Yes, Qt, the most fearsome threat Microsoft has ever faced. It must be destroyed by any means possible! It's available on Windows desktop, Max OSX and desktop Linux and I can't think of one commercial software vendor adopting it rather than products like Visual Studio and .NET, but somehow it's going to take over the world when it's on a Nokia phone! That way people can write software that works on a non-existent MeeGo and a dying Symbian - it's unstoppable!
