I read the iMore review before making the jump from the free PocketCast app to the Instacast Pro app. The one thing that was never mentioned and should have been considered in the playback comparison was that Instacast can not be closed to the Springboard while in a video.
Although I know iMore is not the final say in my purchase, this is a huge set back for me as I download the videos and choose to listen to audio if I am in a situation where video is not possible (e.g. Driving)
You never have to leave the app while listening and following along but if you choose to close the app, Instacast will continue to play on in the background.
Unless I am missing something within the app, which I hope someone on the forums can correct me, I would like to see, if possible, an edit in the review of the three apps as I think this could be a decision factor. Other than this one thing, I am enjoying the rest of the app.
