On Thursday Tim Cook and company took the stage in Cupertino to make some new Apple hardware and software announcements. In addition to announcing an updated iPad Air, iPad mini, iMac, and Mac mini, Apple also dated the next version of iOS and OS X both coming in just a few days time. For the full scoop, jump after the break.

iOS 8.1

On Monday, Oct. 20 Apple unleashes the first major update for iOS 8, version 8.1. Along with bug fixes and some new features (Camera Roll is making a comeback!), 8.1 will most significantly enable Apple Pay on iPhones and iPads. Apple Pay, essentially, takes advantage of your phone’s built-in NFC chip allowing you to make contact-less and secure payments at retail destinations both physically at stores and online. Currently NFC chips are only built into the new iPhone 6 and 6 Plus meaning Apple Pay is fully functional on those devices specifically; on iPads with Touch ID you’ll be able to use Apple Pay with supporting online retailers only. In addition to Apple Pay going live, 8.1 also brings iCloud Photo Library; every photo and video you take will automagically use the cloud to stream across all your iCloud-enabled devices, if you so choose to let this happen. Every edit you make will also take effect across devices, and photos will retain their original format and resolution. Of course, this new feature uses your iCloud storage which you have 5GB free to start. Apple offers various paid tiers up to 1TB at monthly costs. iOS 8.1 is a free download on Monday.

Side note: Cook briefly mentioned the Apple Watch at today’s keynote. Its “early 2015” release is still on track and the company will be releasing a WatchKit SDK in November so developers can start working on ways to integrate their apps.

OS X Yosemite

The next version of OS X dubbed Yosemite (10.10) releases for free today, Oct. 16. Download and install it from the Mac App Store now. Learn more about Yosemite and its fresh new design, Spotlight search, iCloud Drive, Continuity and Handoff features, and enhanced versions of native apps like Safari and Mail right here. Updated versions of iWork for OS X and iOS are also available for free to download today.

iPad Air 2

Apple’s created the “world’s thinnest tablet” with its second generation iPad Air measuring at 6.1mm thin. That’s 18 percent thinner than the original Air. Get this: you can stack two iPad Air 2s on top of each other and that’d still be thinner than the original iPad that released in 2010. Updates all around here. Apple has optically bonded the layers that make up the iPad’s 9.7-inch Retina display: essentially, users will notice an even sharper image. “It makes the graphics and the text feel like they sit right on top and you’re touching them with your finger,” said Apple’s Phil Schiller. Plus, an applied anti-reflective coating reduces reflection by 56% making the Air 2 have the “lowest reflectivity of any tablet.” The new tablet is powered by a new generation chip, the A8X, which features a 2nd-gen 64-bit architecture, 3 billion transistors, 40 percent faster CPU and a GPU that’s 2x faster than the first Air. It’s also got a M8 coprocessor which tracks motion, calibrates internal sensors, and a barometer that measures relative elevation. The A8X and the M8 work in harmony to help maintain a 10-hour battery life. Around back the Air 2 sports a new 8-megapixel camera featuring 1.12 micron pixels, f/2.4 aperture, and it shoots 1080p HD video. An Apple designed image signal processor baked into the A8X chip helps produce stunning photos. And now on the iPad you can take large panorama pictures with up to 43 megapixels, utilize Burst Mode for high-speed action shots, timelapse, slo-mo video at 120fps. On the front there’s a new FaceTime HD camera with a larger f/2.2 aperture that allows in 81% more light than before. It also boasts improved face detection, burst selfies, single-shot HDR photos, and HDR videos. Also inside there’s faster 802.11ac WiFi with MIMO (up to 866Mbps, that’s 2.8x faster performance) and faster and expanded LTE with more bands (up to 150Mbps and 20 LTE bands). And at last the iPad now includes the same Touch ID sensor cooked into the Home button that’ll securely unlock your device just like it does on the iPhones.

The iPad Air 2 comes running with iOS 8.1 and it comes in three different coats: space grey, silver, and now gold. It starts at $499 for the 16GB WiFi-only model and prices increase by $100 more to upgrade to the 64GB and 128GB models. WiFi + Cellular models also exist starting at $629; again, these models jump $100 as you increase storage capacity. It is available to preorder tomorrow, Oct. 17 and they’ll begin to ship “by the end of next week,” says Apple.

Note: Apple will continue to sell the original iPad Air (starting at $399).

iPad mini 3

Not much has changed with the new iPad mini 3. It features the same 7.9-inch Retina display, 5-megapixel iSight camera with 1080p HD recording, FaceTime camera, and 802.11n WiFi with MIMO. There are two main differences here when comparing this mini to the previous generation: it’s got Touch ID and, like its new bigger sibling, now comes in gold in addition to space grey and silver.

Pricing starts at $399 for the 16GB WiFi-only model and just like above that cost increases by $100 if you choose to get a larger capacity: $499 for the 64GB model and $599 for 128GB. WiFi + Cellular models start at $529. Preorders begin tomorrow, and they’ll ship out later next week.

Note: Apple will continue to sell the iPad mini 2 (starting at $299) and the original iPad mini (starting at $249).

27-inch iMac with Retina 5K display

Apple’s bringing its winning Retina display to the all-in-one iMac, specifically to the 27-inch model. The new display boasts an incredible resolution of 5120 x 2880 pixels, containing 14.7 million pixels and making it the “world’s highest resolution display.” Apple’s calling it the Retina 5K display. For comparison’s sake, there is 7x more pixels on the iMac’s new display than on a 1080p HDTV and it contains 67% more pixels than 4K. Yeah. Fun fact: the display uses 30 percent less energy than before, which is nice. The iMac’s bezel remains the same 5mm thinness, as does the rest of its design and I/O. Configuration starts with Intel’s 3.5GHz quad-core i5 processor (upgradable to 4.0GHz quad-core i7), AMD’s Radeon R9 M290X graphics (upgradable to R9 M295X), 8GB memory, and 1TB Fusion Drive. Thunderbolt 2 support is here (two ports around back).

Pricing starts at $2499 and it ships today.

Note: Apple will continue to sell the standard (non-Retina) 27-inch iMac (starting at $1799) and the 21.5-inch iMac (starting at $1099).

Mac mini

For the first time in some time Apple’s upgrading its Mac mini desktop machine with fourth-gen Intel Core processors, Intel Iris and HD Graphics 5000, PCIe-based flash storage, 802.11ac WiFi, and two Thunderbolt 2 ports. Apple names it the “world’s most energy efficient desktop.”

The new mini starts at $499, a hundred bucks cheaper than before and it ships today.

That’s a wrap! Look below for a few videos highlighting the iPad Air 2 and the iMac’s new Retina 5K display.
