Digital Picture Frames

Anyone know what would be a good digital picture frame that I could get my Grandma so she could just carry it in her purse to show images to people? It has to be really simple stupid. Nothing other than clicking a button to change the image or she won’t use it.

I got one of these a couple weeks ago. It’s not too bulky for the size of the screen. While not as large as a 4x6 print, it’s not so small you have to squint. It also has a rubberized finish so it doesn’t slip out of your hand easily. The image quality is surprisingly good for the price of the device. Just copy the files to an SD card and slip it in.
