I don't recall saying that it is or is not in my post above. Please don't put words in my mouth.
but it is not nearly as good a platform for developers as Ubuntu by any means
you are painting a pretty broad stroke there.
I do web and mobile development, both require application like Photoshop, professional video editing tools while web specifically Chrome, Firefox, Safari, Opera and IE, Flash and a few others. For me Linux is not a superior development platform because getting some of these running is just as hacky as getting libs to work correctly on OSX. I use Netbeans as my development IDE which is available on OSX and I have to run a virtual for IE so for me OSX offers a happy middle-ground because I get iOS development while only having to trade running IE in a virtual. So while Ubuntu may be a superior development platform for what you do, it may not be for other developers. The original poster specifically highlighted web development tools. And for web development OSX offers a good value proposition. It has its frustrations just as other OS's do.
