Hi, I have an iPad PRO 12.9". With the large screen, loud sound and good battery life, it is great for surfing the web or watching videos. However, some of you may disagree, I found it not useful as a productivity device. When the iPad OS Beta came out, I was very excited about it and even bought a Logitech keyboard. Then, the excitement worn out and I found that in practice, it is not as good as a 2 in 1 laptop such as the Yoga C930. For example, iPad Pro can only have two windows side by side while in 2 in 1 machine, we can have overlayed windows. We can also develop software and run Windows programs. Moreover, there are still some compatibility issues between iOS browser and some sites such as Blackboard. After using Yoga C930 last year, I feel that I wasted money to buy an iPad PRO. Certainly it cannot be used to replace a computer for my work.
