I've been looking at them for a number of reasons (gifts, subscriptions that don't exist on Xbox yet, etc) and I'm trying to figure out something. What's the difference between the Roku LT ($50) and the Roku HD ($60). The comparison chart on the Roku website doesn't indicate any difference. At first I thought the LT doesn't stream HD content, but it seems (from the aforementioned chart) that both the LT and HD stream 720 HD, while you have to pay more for the XD or XS to get 1080 HD.

Specs for each (from the Roku website) are below. Anyone have advice for me?
