I'm thinking about buying a Vaio Pocket and I've got a few questions. First, does the dock need to be plugged into a power outlet if you want to use the features on it (camera transfer, line out, computer transfer)? I ask, because this would sort of defeat the purpose of tranferring directly from my camera, as I can't use the dock in the field. Also, could you explain how the album art works on the player? Does it read id3 art tags, or do you need to transfer album art as seperate jpgs? All of my mp3s are tagged with album art, so it would suck to not be able to take advantage of that. Last, can I transfer files off of the player back to my computer? Thanks in advance.
