iOS 10 not compatible with 40 percent of mainstream iPads

Earlier this week, Apple unveiled its next-gen mobile operating system. Unfortunately, iOS 10 also carries some bad news - it is not compatible with about 40 percent of the iPad tablets currently in use. Two of these tablets are the popular iPad 2 and iPad mini, with a market share of 17 percent and 15 percent.

Right now, all iPad tablets that Apple ever released can run the latest iOS version, with the exception of the first iPad that launched back in April 2010 and was discontinued in 2011 after shipping around 15 million units. Unfortunately, iOS 10 will launch this fall, and three more iPad models will join the old first-gen iPad. These soon-to-be-outdated models are the iPad 2, the iPad 3, and the first-gen iPad mini.

The next-gen iOS release comes with an attractive set of new features aimed at tablets, especially split screen tabs for Safari. Advertised by Apple as "the biggest iOS release ever," iOS 10 also opens Siri and Maps to third parties and packs a lot of minor tweaks and improvements. The developer preview is already available, and the first public beta is expected to show up in July.
