Microsoft makes a lot more money on Windows than Apple does on OS X, so they spend more money improving it. A lot of that money comes from corporations with expensive, legacy software, so Microsoft has to maintain backward compatibility. That&#x27;s a lot of extra work that Apple doesn&#x27;t usually seem bothered to do.<p>Slimming an OS down as it gets older is also not something that&#x27;s done quickly or cheaply. I also noticed that OS X became more and more bloated since Lion. Mavericks was the last really usable version to me, although I always did have to install a bunch of third-party tools to get the UI to behave in an efficient way.<p>I think you&#x27;re totally right, but there are some people who have an almost religious, fact-free hatred of all Windows versions. I don&#x27;t see too many OS X fanboy posts anymore, though.
