You shouldn't be reading books on an iPad. You will screw your vision. I only read long forms on iPad (that takes 10-15 minutes), nothing more.
I think I need a kindle for dedicated reading. I hate getting notifications that interrupt my reading lol.
I voted 5S and iPad because the 5S is still a very current phone and the iPhone 6+ is not an iPad mini replacement for me.
From a minimalist standpoint, the fewer devices, the better
Reading on the iPad Mini Retina for me is nice and sharp. No eye fatigue issues. Should be about the same as the Kindle Fire HDX, right?
But I can't follow my fantasy football team and plan Clash of Clans on a Kindle Paperwhite!![]()
6+ over the 5s. But the iPad can be something you use whether or not you have the 6+ or not, there's still a valid case for it because browsing on a wider screen device is so much better than not having it.
I have an iPad, a 6 Plus, and a Paperwhite. Between the iPad and the Paperwhite, I prefer the Paperwhite. I don't need to go into why eink is better for sustained reading. But between the Paperwhite and the 6 Plus, I use the 6 Plus way more. Why? Because it's always with me. And I know it's already charged. I know I can sync the books anytime, and download new ones without worrying about being connected to wifi (or dealing with the super slow connections trying to navigate a store or menus on an eink screen). The text looks fantastic on the 6 Plus screen, and I don't have to scrunch it up to my face to make it readable. The 6 Plus has me reading more again, because I can pull it out anytime I have a free moment and read a few paragraphs or a chapter out of a book. It's great for that.
If you're reading ebooks at home, I highly recommend a dedicated eink e-reader, but if you read them mainly on the go, the 6 Plus is the perfect device for it.
As for an iPad and phone vs just the phone, it depends on your usage. I have an iPad Air and I'm not giving it up even though I have the Plus because the size difference is significant and it's perfect for reading comic books. I read a ton of comics, and the Air is close to the original print size, so I can read them with little compromise. I can't do that on any other device that runs iOS currently.
Any backlit illuminated screen is bad for your eyes. It's like watching a lightbulb. I know it seems ok and comfortable and all, but when you'll be in your forties and fifties it will start showing up. There's a reason why ebook readers have that edge lit illumination so you never see the source of light.
I prefer the 5s and mini retina combo. Wife prefers the 6+ though.
I'm a one hander on the iPhone and found the 6 annoying to operate in one hand. I like the design of the 6 and hope they release a 6s in 4".
