So I'm thinking about getting a tablet for my Dad as a Christmas present but can't really justify the price of an iPad since he will likely never use any app outside of Amazon Prime Instant Video, Kindle for reading, and a web browser.* Obviously, the subscription to Prime he already has leads me to consider the Kindle Fire HD, specifically the upcoming 8.9-inch model as he thinks the 7-inch tablets are too small.* My question is then: how is the Amazon Silk browser for those who have the 7-inch Kindle Fire HD? How do you like it compared to the iPad Safari browser if you've used both? Is it frustration-free to use a term Amazon itself uses? Is the modified Android environment easy to use/learn compared to iOS? How is the screen responsiveness compared to that of the iPad, considering it runs $200 less than Apple's iDevice? I would also ask about the image/screen quality but not sure anyone could answer since the 8.9-inch model isn't out yet.
