The iPad Air is a marvelous tablet. It's the perfect medium to read books, watch web video, check your e-mail, and play your favorite games. But the iPad Air has been on the market for nearly half a year. While the iPad Air may not be on its deathbed just yet, technology moves fast and Apple's best tablet to date is almost certainly experiencing a midlife crisis. So what could we expect in a new iPad Air? For simplicity's sake, we'll just call it the iPad Air 2.

Obviously the second-generation iPad Air 2 will be faster. That includes customary updates to the graphics and processing chips, and perhaps more RAM for the first time in a long time. Yet, the iPad Air 2 won't just be receiving a slight performance boost this time around. With reported quad-core graphics and a quad-core processor coming to the iPhone 6, the iPad Air 2 will likely get the same chipset, albeit at slightly faster clock speeds.

The iPad Air 2 will likely include a hardware feature known as Touch ID, currently only found on Apple's iPhone 5s smartphone, that will go along way towards making the tablet much easier to use. And ease of use also implies faster. 

Another feature, and mind you this is all speculation, is a sapphire screen. If Apple can produce nearly 100 million sapphire screens for the rumored iPhone 6 phablet than why couldn't it produce a sizable amount of screens for an iPad Air 2. If it can get the cost down, then we'll likely see the new, super-strong sapphire displays on an iPad soon.

Laptops are too heavy and phones are too small, thankfully great tablets like the iPad Air exist. Will the "air" apparent to the current flagship iPad be as great as we think it may be? Let us know in the comments section below.
