Ranked in these QuestionsQuestion Ranking
Pro Very thin and light
The Apple iPad Air 2 is only 6.1mm thick and weighs less than a pound
Pro High resolution display
The 9.7" display has a resolution of 2048x1536, which means it has 264PPI (pixels per inch). The display is bright and super crisp
Pro Optimized apps
Android and Windows tablets have nothing on the iPad when it comes to apps. Windows apps are mostly meant for desktops, while Android tablet apps are more often than not just up-scaled versions of the phone apps, which doesn't make good use of the extra screen space that tablets offer. On the iPad, there are hundreds (if not thousands) of apps optimized to work specifically on the iPad.
Pro Simple authentication
Apple uses their own fingerprint scanner, and you can use this to authenticate purchases even in third party apps (if they support it).
Pro Great screen
The high resolution of 1536x2018 makes for a crisp 264 PPI (pixels per inch). It gets very bright (401cd/m2) and also offers a great contrast ratio (1019:1).
Pro Amazing performance
This is the first time Apple has put 2GB of RAM into a tablet, and alongside the new A7 chip it screams. In 3DMark (ultimate) it scored 128fps, beating out all the competition handily.
Con Not very customizable
If you buy an Apple product, hopefully you like Apple's way of doing things. While the iPad does support third party keyboards and replaceable default apps, neither of these functions work as well as Android tablets. You're also stuck with the default home screen layout.
Con Videos have larger black bars
Because of it's more square 4:3 aspect ratio, HD movies will play with bigger black bars on top and below than most other tablets. The 4:3 aspect ratio does make it more comfortable to hold and use however.
