The iPad Pro is heavily rumored to be Apple's next tablet. Currently the consumer electronics giant sells the two-year-old iPad 2, the iPad Mini with Retina Display and the iPad Air. While those three products are very similar to each other barring physical size and screen dimension, the iPad Pro will likely be similar to the Microsoft Surface line of tablet computers.

The iPad's biggest detractors have always complained that the lack of an official keyboard accessory like the Surface makes it a useless productivity device. These people aren't crying over spilt mile. Typing on a touch screen is not pleasant at all. If your iPad is jailbroken you can install a custom onscreen keyboard, but the experience still falls far short of ideal.

Could the iPad Pro address that and other productivity issues going forward? It the iPad Pro is truly a professional's best friend it will certainly make all of this criticism moot. But even a "perfect" product wouldn't appease everybody.

The iPad Pro is also rumored to be shipping with a super duper spiffy 4K resolution. The display will be also be 12.9-inch. 4K display is graced with a resolution quadruple that of convention high def television. In a nutshell, the iPad Pro would be the highest resolution tablet on the market.

With a display that clear you may not want to dirty it up. That's where eye-tracking comes in handy. Instead of controlling the iPad with your oily hands you may be able to make specific gestures in the air similar to what the Samsung Galaxy S4 is capable of. If eye-tracking does come to pass, expect it to be implemented tightly into iOS 8's operating system.

The only thing worse than getting your iPad's screen all oily is accidentally scratching it. Gorilla Glass has always been Apple's answer for scratch protection on its iDevices, but it may elect to use its own machinery this time around to manufacture an impervious sapphire glass display for the tablet. Smaller sapphire glass panels look to be included in the upcoming iPhone 6.

No one knows for sure when the iPad Pro will be released.

How would you use an iPad Pro? Do you think it will be different enough than the iPad Mini with Retina Display and iPad Air? Let me know in the comments section below.
