Unless you have unlimited storage you have to worry about running out. It would be nice if PlayLater could delete certain shows or channels that I subscribe to after a certain period of time without me having to manually delete them myself using my computer. It would be nice if PlayLater could handle the deletion of videos from certain channels/shows that I specify after a certain period of time so I wouldn't risk running out of hard drive space. Some videos can be >1GB in file size which can add up quick.
