Amazon's (AMZN +0.2%) Fire TV set-top (live blog) is a small, rectangular box sporting a quad-core CPU, 2GB of RAM, and a dual-band Wi-Fi radio. As expected, the device supports both Amazon's media content and a variety of 3rd-party sources (inc. Netflix, YouTube, Hulu Plus, and WatchESPN).
Amazon asserts the Fire TV's CPU leads it to exhibit far less lag than Apple TV, and that its UI makes searching for content far easier. Voice search is supported, as is a feature called "ASAP," which attempts to predict which shows a user will want to watch.
The event is ongoing. Amazon hasn't yet announced any gaming features (previous), but it has shown a UI screenshot that reveals a "Games" menu.
