Group Video Calling will be free at first, but Skype has plans to bundle it with upcoming features and eventually — in three to four months time — charge for the additional functionalities.
There have been rumors that Apple will sometime soon, maybe even on September 12, announce downloading of videos but Amazon has beaten them. See Unbox.
So far it’s only available in the US.
The fine print says that the Unbox player is required, and the movies are not compatible with Apple hardware, including iPods. The downloads are viewable for up to 30 days, and after you commence viewing the video you have 24 hours to complete it.
Update: although Unbox is available, there aren’t too many positive reviews. For example, see the CNET review and user comments
