Some people are simply never going to find a tablet (of any make) comfortable for reading. You have to repeatedly tap the screen to turn pages, so you can't hold it in two hands like you might an open book. You can't hold in one hand the same way you might hold an open book with one, as the home button is front center where your thumb would fall. OK, you CAN rotate the screen around to another side. It's still not a book, and some folks can't comfortably hold up a book either.
The iPad is twice as heavy as the Kindle, and I still find my Kindle awkward to prop up or hold when I'm entranced by a good read.
I'd look for an anti-gravity case. One that will suspend your iPad floating in front of you.
