I like the slim frame on this 8.4 inch high resolution screen and also the way that you can display both pictures and video with sound or music.
If you have landscape and portrait photos the frame will automatically show them in the proper orientation. It's also really useful to be able to insert a card into the external memory card slot, although it could be quite a while before you need to do that because the internal memory on this baby is a massive 2Gb. That adds up to a LOT of photos.
Another excellent feature is that you can use the frame as a clock and calendar when you're not looking at your pictures, which makes this ideal for anyone with limited space on the wall or shelf. Why have two things when you can have one?
