Well, I don't have the iPhone, so I don't care about the feature integration with El Cap. I mean, I can understand if you do have an iPhone that it might be a terrific feature. But as for making/receiving calls from my iMac - a big LOL, because I can do that already through Hangouts... as a matter of fact, I'm on T-mobile and in my area the cell coverage is poor, and people MUCH prefer the excellent quality of Hangouts through wi-fi... and even there it's kind of funny, because I no longer use Hangouts through my iMac, but through my iPod Touch (latest generation) - works brilliantly! So from that point of view, El Cap does nothing for me.
In general, I know it's super cool to hate on Google these days, but man, I gotta say, without Google and their apps, the experience of iOS and OS X would be so much worse... I don't even mean search (Bing or Yahoo anyone, lol?), I mean things like Gmail, Google Docs, Google Maps (Apple's maps don't come anywhere near), Chrome browser (which has always worked better for me than Safari) - sorry, but I'm all in on Google stuff making my life so much better on Apple hardware - yep, lol, Apple hardware! Apple should go and kiss Google's feet, because they make apps for Apple - without which, relying on Apple's lame stuff life would be so much worse.
Instead of bashing Google, Apple should figure out why they are so bad at so much of the new tech, including stuff like Cloud - at which they've always been bad... anyone remember how you could get your email through Apple, and how you had to pay and and how Gmail came along and blew it away? Or how often the various sync functions would fail - to the point that even Steve Jobs upbraided his engineers and developers "you should hate each other for letting yourselves down". I don't know what it is, but Apple just can't do any of this stuff anywhere near as well as Google (and others).
What Apple does well is hardware (which is why I own so much of it) - it's nice... not the most powerful necessarily and not the best bang for the buck for sure, but it's well-done, well-finished, well-thought out (for the most part - forget the mouse though) and just a pleasure to look at and use, an aesthetic triumph. But they've gradually lost the plot with their OS X (Snow Leopard was their high point), and apps (gave up on much of the pro market, such as photo editing when they finally killed Aperture). And they've been playing catchup - badly - with the internet since day one... just no good at it at all, and Google runs circles around them. So when I read about all the iCloud-this and iCloud-that and various "features" of El Cap and now Sierra... all I can muster is a big "meh". Not excited at all.
I'm staying with Mavericks and Google, thank you, for as long as I can... which may not be that long as I need to buy a new iMac pretty soon, since my late 2009 iMac (which I actually bought early 2010) is getting long in the tooth. And with the new iMac will come a new "improved" OS, lord help me.
What Apple needs is competition. Google spanks them in applications, but nobody comes close in hardware - Apple is still far and away the best, with nobody even close. As for operating systems - it's bad all over... nobody is perfect or much ahead. We'll see what happens.
