I wish they had an "mini" version of the iPad mini, and I wish they allowed you to drag-and-drop files onto the device, like Android does.
I used to have the Nexus 7, and I loved it--I could even fit in some of my front pants' pockets. Also, it was $100 less than the IPad Mini MSRP.
The closest thing I've found for drag and drop is iOs Files App.
Can't help you with your pockets.
