Two things I miss this!
a.) a reasonable search that can be limited exclusively to Prime Instant Video and me not even any books, DVDs or other shows, which could possibly even match my search. Seeking already in the app and not in the normal shopping app.
b.) the possibility of movies for "borrowing period" to load locally down, so that they. can there watch, if necessary, where there is no stable internet connection or where you do not necessarily wants to use his mobile phone tariff to the stop on the streaming.
If these two things could be implemented (and I still could specify the location on my SD card), I was really happy about the part. So I use the app rather rare, as I usually have the rule over one of my remotes home and prefer to look at the movies on my Blu-Ray player or my Playstation on the television.
