I dunno, it's really cheap anyways. The streaming service is roughly the same quality as Netflix, but you also have the option of purchasing newer releases for streaming for a seven day period. So it's sort of like Netflix combined with On Demand. Plus you get all the free express shipping stuff, which is nice. Mostly a worthwhile expense, IMO, particularly if you have a Kindle Fire.
But you're right about the fact that Netflix has apps on everything, which still puts it head and shoulders above all else.
