Apple has had its greatest success with its Apple iPhone and iPad. Certainly, Apple Computer built an awesome interface with Macintosh and later changed the name to Mac and changed their company name from Apple Computer to Apple, Inc. In a little over 10 years their stock skyrocketed from the 20's to over 500 with a couple of stock splits on the way.
Unfortunately some idiots in control at Apple have decided to merge the interface of the successful iPhone and iPad user interface with the desktop interface -- presumably because of the success of the mobile devices. The problem is a computer is still a computer, or a desktop is still a desktop, or a laptop is still a laptop. Desktops and laptops don't need super skinny scroll bars like the iPhone does. They might not even need all of the touch gestures that the iPhone or iPad need. Sure Apple's mobile devices have excellent user interface design, but their success doesn't mean that mobile features should be incorporated backward into the desktop design, at least not at the expense of the desktop operating system.
