Same price, the only differences are that the Fire TV has voice search (don't care), a bunch of technical specs that the layperson doesn't care about, and a bunch of games (don't care). It's missing the checkbox for HBO GO (deal breaker for me personally).
I was expecting something like a monthly subscription for all-you-can-watch access to any TV show on Amazon Instant (not just the free Prime episodes). Kinda bummed because I really like Amazon as a content provider, but I'll be sticking with Roku for now.
