Everyone on this thread has brought up some good points. I tend to agree with those that posit that Apple has lost a step or 20 in recent years.
For me, it's been a gradual, steady process that started around when Steve died.
First, it was the move to their new OS design language. I find iOS 7 (and now Yosemite) vastly inferior to their predecessors aesthetically. And when it comes to Apple, aesthetics is what brought me to the table in the first place. I know the hardcore prefer Snow Leopard (and rightly so), but Mountain Lion and iOS 6 were the perfect combo for me.
Skeuomorphism in OS X and iOS was beautiful, detailed, and intuitive. Now it's been replaced with Google-like austerity, simplicity, and Spartan-like cold functionality. I feel Google does that better, so I use that instead of Apple's version. And I also prefer Windows flat approach over Apple's; it is both original, fresh, and far more interesting aesthetically in my opinion.
Apple also started to really lock down their walled garden when I couldn't even go back to the iOS version that I loved and came with my phone.
Then they killed-off of the CMBPs (the 17" especially), and with it easily accessible and replaceable internal components, which they carried onto...
The killing of the Mac Pro, turning it into a super-niche-closed-box.
Why not sell all these alongside the niche and ultrabook (i.e.Retina MBPs) variants? They still sell the (unacceptably crippled and un-updated) 13" cMBP!!
Finally, the Mac Mini became what it is today. Sigh.
So I don't even watch keynotes anymore. My fragmented ecosystem works just fine, and I refuse to be locked down ever again. Apple simply doesn't make anything I want anymore. They can keep their ridiculous watch.
In short, I like the classic, Steve Jobs-Apple. The new Apple? Not so much, if at all.
As a side note:
The PowerMac G4 remains to this day as the most beautiful computer I have ever seen. If Apple ever built a 27" variant (or even a 20" like they used to) with Mac Mini internals (without soldering everything down), I'd stand in line to buy one--which I've never done for any product.
My first Mac was a 17" Powerbook G4 1GHz--the first 17 they released.
It's fitting that my last Mac may be the last 17" they did.
