New products helped post record revenue figures for Apple during the last quarter - though company shares slumped dramatically in after-hours trading.
Shares dropped by as much as 7.5% in the 30 minutes after trading in the US, as its lofty iPhone sales predictions fell slightly short of initial predictions.
It was the first period fully taking into account sales of the iPhone 5s and iPhone 5c, as well as marking the launch of the iPad Air and iPad mini.
According to new figures, Apple's revenues hit 57.6 billion US dollars for the last three months of 2013, a new quarterly record for the company.
Profits of 13.1 billion dollars were also made - equal with the record profits set 12 months previously.
Apple sold 51 million iPhones - a new high for the company, though short of forecasts peaking at 60m - while iPad sales also set a new record of 26 million.
The company also sold 4.8 million Macs, compared with 4.1 million in the year-ago quarter.
Tim Cook, Apple chief executive, said: "We are really happy with our record iPhone and iPad sales, the strong performance of our Mac products and the continued growth of iTunes, software and services.
"We love having the most satisfied, loyal and engaged customers, and are continuing to invest heavily in our future to make their experiences with our products and services even better."
The figures reverse a slump in revenue - from the all-time high a year earlier (54.5 billion dollars), to subsequent figures of 43.6 billion dollars, 35.3 billion dollars and 37.5 billion dollars.
Last quarter, Apple sold a record-breaking 33.8 million iPhones but experienced a drop in sales of Mac computers.
Peter Oppenheimer, chief financial officer, said: "We generated 22.7 billion dollars in cash flow from operations and returned an additional 7.7 billion dollars in cash to shareholders through dividends and share repurchases during the December quarter, bringing cumulative payments under our capital return programme to over 43 billion dollars."
Apple expert Professor Loizos Heracleous from the Warwick Business School said the figures showed the technology superpower had sustained reasonable growth.
But he identified areas of concern for the business and shareholders. "Even though Apple has achieved record revenues and profits, the growth rates of its leading products (iPhone, iPad) are reducing. This means that to recapture the rates of growth that Apple historically delivered, there should be new product introductions of the calibre of these leading products," he said.
"Despite lower growth rates, Apple remains a solid company with enduring competitive advantages. These include its prowess in design, marketing, innovation, ecosystem creation, and intense operational efficiency.
"Even if historical growth rates are not maintained, these competitive advantages are hard to beat by competitors at least in the near-to-medium term."
HTC One M8
The 2014 update to the HTC One builds on the same hardware features that won the original such a fanatical response, but keeps the essential DNA intact. The massive front-facing speakers are 25% louder, the UltraPixel camera adds a second lens for depth perception (so you can refocus an image after shooting it), and there's a 5-megapixel 'Selfie' front facing lens too.

Sony Xperia Z2
Sony's latest flagship Xperia smartphone is a beautiful, thin and waterproof delight. It packs in a 20-megapixels still camera capable of 4K video, a sleeker form factor, a far better screen and built-in noise cancellation technology.
Samsung Galaxy S5
This year's Galaxy S adds water resistance, a slightly larger screen, a 16-megapixel camera and a heart-rate sensor into what was already a market-leading, powerful and sleekly designed device. It doesn't rock the boat too much, but it didn't need to. This is still up there with the very best Android phones.
Google LG Nexus 5
The new Nexus 5 is based on the internals of the LG G2 - which means you get the same Snapdragon 800 processor, as well as the full version of Google's new Android 4.4 KitKat OS, which integrates SMS messages into Hangouts, freshens up the design and adds new features under the hood. The camera is still a little lacking, while the design is functional rather than beautiful, but at £299 off contract it's still a steal.
The 5C was rumoured to be Apple's 'budget' iPhone. It isn't - and not only because it isn't that cheap. The "proudly plastic" 5C comes in five colours (see what they did there) <a href="http://www.huffingtonpost.co.uk/2013/09/10/iphone-5c-uk-pictures-release-date_n_3899557.html?utm_hp_ref=uk-tech" target="_blank">but has the same internals, screen and camera as the iPhone 5.</a> It's essentially the same beautiful, high-end phone you already know and love, in a more colourful (and potentially divisive) design. As such it's hard to see how Apple won't sell a billion of them.
Nokia Lumia 925
<a href="http://gdgt.com/nokia/lumia/920/" target="_blank">The Nokia Lumia 925</a> has the same great design and attention to detail we've come to expect from Nokia, but with some crucial upgrades from the 920 including a thinner, all-metal design and an improved camera.
With the same ultra-clear Retina display as the iPhone 5, but now with an <a href="http://www.huffingtonpost.co.uk/2013/09/10/iphone-5s-uk-pictures-release-date_n_3898775.html?1378818683&utm_hp_ref=uk-tech" target="_blank">added fingerprint sensor</a>, a seriously impressive 64-bit A7 chip, an improved camera and a new gold design option, this is the best iPhone ever made. And with its consistent market-leading app selection, easy-to-use OS and delightful design, it's hard to argue against it being one of the very best gadgets ever made too.
The LG G2 is an extremely high-end 5-inch, 1080p Android 4.2.2 smartphone whose major distinguishing feature is that it has three buttons on the back of the device, which are normally found on the sides. The G2 has its camera button and volume rocker on the rear, which for many people is enough to justify the purchase alone. It also has excellent battery life for this class of device.
Samsung Galaxy Note III
The Note III is huge. It's got a 5.7-inch screen, though with the same 1080P resolution as the Note II. It adds a new leather back panel, which gives it an 'office' feel in line with the productivity-plus-stylus theme of the device. It also adds a Snapdragon 8000 quad-core processor, some new software enhancements and a few new S-Pen functions into the mix. If you're looking for a giant note-taking phone, this is still your best bet.
