18. I have an IPad and I gave my Dad a Kindle Fire
He's elderly, so he loves it because it's light and not as difficult to hold onto. The biggest pain with the IPad is you have to keep your hands around the edges when you want to move it. The touch screen is so sensitive, you lose your info every time your fingers stray. It's easier on the Kindle.
I'm an Apple person, so dealing with Android Apps isn't natural for me. Also, I was bummed you couldn't put ITunes on the Kindle. Don't see why not, since I have it for my PC as well as the Mac. But to compensate, the Kindle has Adobe Flash and the IPad doesn't.
Also, Dad and I both have the MLB At Bat app, and can watch every baseball game we want on our respective tablets. Streaming is awesome on both, just the IPad has a bigger screen.
So both are good choices, just depends what you want them for. Music, photography and graphics are always better on Apple products!
