This is a beast of a review, lots to digest. To start things off:

“Huge for developers. Massive for everyone else.”

That was Apple’s tagline for iOS 8 when the software was announced at the company’s Worldwide Developers Conference back in June. Overuse of hyperbole is a pet peeve of mine, but after using iOS 8 for a couple of months, I have to say that they’re warranted in this case. iOS 7 was a comprehensive makeover for an operating system that needed to reclaim visual focus and consistency. iOS 7.1 improved stability and speed while addressing the new design’s worst shortcomings and most egregious excesses. And iOS 8 is the update that turns its attention from the way everything looks to the way it works.

What’s huge for developers is the fact that Apple has opened up much of the OS for customization.

Apple still holds the keys to many aspects of the iPhone and iPad user experience, but compared to past versions of the software iOS 8 represents an opening of floodgates. Don’t like Apple’s software keyboard? Replace it. Want sports scores and updates on your eBay auctions in your Notification Center? Here’s a widget, throw ’em in there. Want to use a social network or a cloud storage service that Apple hasn’t explicitly blessed and baked into the OS? Cool. Here are some APIs for that.

As you make your way through the various reviews, keep in mind that the best of iOS 8 is yet to come. As developers wrap their heads around what’s possible, clever bits of code that leverage your iOS experience will start to emerge. That’s when the true value of iOS 8 will become apparent.
