Apple started with the size of the iPad. The Air 2 retains its 9.7in, 2048x1536 resolution screen, although it rests in a body that is 6mm thin. Turns out Apple has shaved the Air 2 down by 19 per cent.

Great performance; Thin at 6mm; Improved cameras; Finger scanner

Expensive; Apple locks its ecosystem

When the iPad first arrived on the scene it took the world by storm and basically brought the idea of tablets into the mainstream. Now, Apple is facing tough competition from other manufacturers and has seen their sales flatten out in the past couple years.

Reduced weight and thickness; Incredibly fast performance; Beautiful display with vibrant colors and deep blacks

Potential issues with bending; 16GB base model not worth the price; No real improvement in battery life

When Steve Jobs introduced Apple's tablet in January 2010 , he delivered an unequivocal answer. "The iPad, if you were to sum it up, is our most advanced technology in a magical and revolutionary device at an unbelievable price," he said.

Terrific display; So very thin; Great battery life; Super fast

No multiuser support; No multitasking; Safari icon still objectively terrible

The iPad Air 2 is undoubtedly Apple's best tablet to date. Its Touch ID fingerprint scanner works well, it's thin, light and powerful and lasts a long time on a single charge. But it no longer stands head and shoulders above the competition.

thin; light; long battery; powerful processor; fingerprint sensor; decent camera

expensive; small upgrade over last year; square screen; no expandable storage

The iPad Air 2 is the best tablet ever created - and that's not us getting excited over an Apple product for the sake of it. From the amazing engineering that got this thing so thin and yet still feeling so premium, to the A8X chip which has given the tablet more grunt than anything else out there,...

Upgraded screen; Slimmer design; Super speedy processor

16GB is a little low on space; No mute switch

But as I tested out Apple's new iPad Air 2 , I see why people like to shoot pictures with a tablet. Images look great on the large screen, and there's less guesswork about whether or not small details, such as lettering on a sign, will be in focus.

Razor-thin, fast as hell, finger friendly, and now in gold: Apple's iPad Air 2 is the best tablet you can buy.

Thinner than any other Apple device; Screen brighter than iPad Air; Powerful new processor is a step up; iPads have best app selection of any tablet; Improved rear camera; Touch ID added

16GB model does not have enough storage; Speaker quality worse than Air 1; iPad Air 1 is $100 cheaper; Not water resistant; No MicroSD storage options

Apple's marketing suggests that the iPad Air 2 is the fastest, thinnest, best iPad Air ever. But they would say that. Is the iPad Air 2 worth buying, or upgrading from if you're an existing iPad owner? First up: My early impressions, and a comparison to last year's iPad Air.

Apple has sold more iPads in the last four years than it sold iPhones in the first four years they were available. And yet, despite these amazing figures, Apple's tablet business is suffering.

The iPad Air 2 is not worth the upgrade if you already have the Air 1. Aside from the enhanced hardware, better camera and Touch ID, there simply isn't anything compelling. The Absence of NFC relegates Apple Pay to being able to make App Store purchases, without having to type in your password.

Anti-reflection screen coating; Faster processing; More RAM; Wireless Connection is faster; Touch ID

Very Minor Upgrade; No Mute button or rotation lock; Apple SIM does not work in Canada or Australia
