MS has backwards compatibility for existing software, but it's a gamble to start a new project using MS tech, you don't know what they will cancel, rename or invent next year. Apple doesn't have backwards compatibility for existing software and stuff breaks regularly from version to version. However, one can count on Objective-C to pretty much work (although Swift is still work in progress). So both suck, basically.
