The lost features are actually found in the similarly priced S610, with the A810 offering a slightly larger screen instead. Supporting protected WMA allows the A810 to work with subscription music services such as Rhapsody. On the video side format support is more limited than the S610 as the A810 is compatible with only MPEG4 video, and no h.264 like the 610 series. Videos and images can be played back in either portrait or landscape more for "widescreen" viewing.
