Thinking about whether or not to pick up an iPad Mini 4 on sale, or even just get something cheap like the Amazon Kindle, as a second tablet and companion to my iPad Pro. I haven't had any issues with the Pro's size overall, and use it everywhere, but there are times where I know it would be easier to kick back in bed with an Air, Mini, or some cheap tablet. Anyone considering or already pull the trigger on the same? Curious how your use cases define which tablet you reach for, and whether or not it's a waste of money to spend the extra $$$ on an iPad Mini (just to stay in the same universe of apps, browser, media etc.) or if a Kindle is the way to go for a lot less $$$ (Fire HD 8?) Or if because I love my Pro so much if either is a waste and I should just stick to a single device (in addition to the iPhone 6s Plus, which I somehow never seem to use for consumption as I do a tablet). Thanks!
