Apple's software has never been perfect-- but the competition was often much worse, so it looked really good. (I switched to Mac because I couldn't take WindowsXP crashing all the time.)
However, now Apple is essentially the iPhone company. The iPhone has a new version, with new hardware and new capabilities, every year. This basically means a new iOS, new apps, and often, new capabilities in OS X (Hand-off, whatever is happening with photo sharing this year, etc), and new features in XCode. (Plus all the watch stuff last year.)
I'm all for being agile and moving fast, but there's just not enough time to do this right. Sure, it might help to have more focus, and they have plenty of people and money. They just don't have enough time.
