Let's be honest here, Mac OS X is a very mature system that runs very stable and is full featured. Why do we need more frilly features? Do you need eye candy to make you feel better about your new OS or do you want it work?
Yeah, sure, Windows 8 is all shiny and new with that ridiculous Metro UI, but let's be honest here, it's something frilly and new and Microsoft thinks they reinvented the wheel, even though it's just an AOL clone. At the end of the day W8 just sucks. Pretty doesn't make for better.
I guess you've never taken into account that Apple may do more things under the hood of OS X so the user can have a better computing experience? You may need Frills, I need a working system and Apple puts that out with Mac OS X so I cannot and will not agree with you that they are neglecting OS X. This has been harped on for years now and frankly it's gotten tiring.
