The issue I have with Windows 8, and OS X.10 is the fact that they are trying to make the OS into the next tablet/mobile OS.
No, they aren't. At least, not Apple.
They are making your Mac work with your iDevice more seamlessly. There's a pretty big distinction there.
Anyone claiming this is akin to Windows 7 -> Windows 8 isn't paying attention. For one, Apple has never (and still doesn't) ship a touchscreen Mac, so it would be quite ridiculous to put a touch-centric UI on OS X. OS X is still clearly ruled by the mouse / trackpad and keyboard, and will be for the foreseeable future for one very good reason - OS X is where the content for iOS is made, and iOS is where the content made on OS X is consumed.
That is the business model for Apple, and very close to what Google is doing too if you haven't noticed. They haven't exactly been whipping people to get Android onto laptops - that's what ChromeOS is for.
