Nice Picture Frame!
I like this frame because it is so simple to use. I was even able to teach my wife how to use it (which is no easy task) in just a couple of minutes. I just need to plug in my card from my camera and it starts showing my pictures right away. And I don't have to worry about deleting all my pictures like I did once with a different frame as this frame wont delete from the memory card. And for my favorite pics, I can copy them from the card and store them in the frame's memory. When I need to put the card back in my camera, the frame is still able to go through all the pics i copied.
