We're particularly keen on the new notification feature. When one of the titles in your DVD Queue becomes available for Watch Instantly, your FeedFlix page will highlight said DVD and display the date the title will expire from Instant View—so you don't need to waste a DVD roundtrip on a movie you can watch right now.
Apart from that, FeedFlix still performs the handy analysis that shows you the relative cost per movie you're paying for your Netflix subscription, so even if you don't use the new Watch Instantly notifications or multiple profile feature, it's still a handy tool to decide whether or not your monthly subscription is worth it.
