The biggest difference between the new K3 and the K5 is that that K3 is believed to be lacking the built-in speaker that made the K5 unique amongst other DAPs. The screen is a little larger, too, this time coming in at 1.8 inches versus the K5's 1.7 inches. Whether or not it's any better at viewing pictures is anyone's guess. There's a higher-res shot after the jump.
After looking at the pictures of this MP3 player I have to admit it looks damn nice.
