The answer is that if you are already having one of the iPad Pros then you can stick with it for now and it will be good for another couple of years. With the launch of these budget iPads, the company hopes to explore a new user base and boost its overall ecosystems. Your new age tablet is a productivity tool.
The new screen is shaping up to be one of the most dramatic changes to Apple's mobile devices since the Retina Display.
Just like you don't need the new iPhone but you want to have it, you will want the iPad Pro.
Apple has updated the specs and capabilities to be identical for both the 10.5-inch iPad Pro and the 12.9-inch iPad Pro. As iFixit put it, the 10.5-inch iPad Pro is just a "scaled down and streamlined version of its 12.9-inch predecessor".
You would think the slight 0.8-inch increase in screen size would be minimal. However, iOS 11 is coming out later this year and it has been anticipated that it will provide a massive update to the iPad software which will add aplenty to Mac-like competencies. The 9.7-inch Pro had it situated next to the rear-facing camera while the 10.5-inch Pro plopped it down next to the selfie camera. But the fact it's not on the iPad Pro 10.5 you can buy today is going to leave you disappointed for now. Neither has it added any new biometric identification system, such as iris scanning that has become more common with other vendors. Apple's own $159 Smart Keyboard feels nice, but it bothers me that there's no place to store the Apple Pencil. The bezel is slimmer but the display is still a long way from being edge to edge, and the functionality improvements are something you appreciate with time.
The 10.5-inch iPad Pro even has the same 6.1mm thickness of the 9.7-inch model, but it is slightly wider and taller.
But, hey, it's the new iPad, it's better than the old iPad, and the new screen is super awesome for apps that support it which right now appears to be limited to only the core Apple apps and a small subset of third party apps.
Combined with ProMotion, this means it will respond better and faster, so you can expect smooth sailing when you bring out the artist in you - even if you just doodle around. The problem here, much like my first impressions of the iPhone 7, is that while 30% and 40% seem like big numbers on paper, the previous generation iPads aren't devices anyone would describe as "slow".
