I'm currently using an iPad Air 2 and I love how fast and fluid it runs. However, soon I will start my hospital internship as a medical student , and I'm considering switching to a smaller form factor. I previously owned the iPad mini 1, and I loved how it fitted perfectly in the lab coat. Before I replace my Air 2, I wanted to know how well the A8 chip runs iOS 9 on an iPad display. I use my iPad a lot, from surfing the web, playing graphics intensive games like Hearthstone, editing photos and rendering 3D anatomy models. I will probably use both the multitasking and picture in picture features. I get limited value from Geeckbench scores, so I was wondering if anyone with hands on experience with the mini 4 could tell me how well it performs the tasks I mentioned above. Thanks!
