Apple TV (formerly known as iTV) requires a ‘widescreen TV‘ in order for it to work properly. Furthermore, Apple says that Apple TV works with ‘widescreen, enhanced-definition, high-definition TVs capable of 1080i, 720p, 576p, or 480p resolutions, and progressive scan DVD player’
Apple has also posted a tour of the Apple TV UI, so if you aren’t at Macworld you can take an Apple TV for a spin.
