I think the point though is that you don't actually really have to do anything. You don't have to get out a cord or drop it in the cradle, you can just go out, shoot some shots, and then come home and turn on your camera and it will upload itself to your computer. Large sized RAW files may take a lot longer to download, but I don't think that the professional photographer is their target on this one. They are going for the average 'I wanna be wireless everything' early 21st century person, and that person is most likely to be carrying a compact camera. So for them, coming home and turning on the camera and then wandering away and doing something else while their pictures are uploading is probably pretty appealing.
Its almost appealing to me actually - I hate getting out the cord for my camera!
