X08D has No Internal Memory
About this aspect:
The X08C/X08D does not have an Internal Memory. It is a Plug and Play frame that simply operates by you plugging in your USB Drive or SD/SDHC Card (with pictures already loaded onto them) into the side of the frame and viewing photos in this manner.
If you seek an 8" Frame with Internal Memory, The Deluxe 8" Pro Series Frame with rechargeable battery has an Internal Memory of 2GB, a Rechargeable Battery that allows you to use the frame in cordless mode for up to 3 hours each time and a different build quality. It also has blue touch controls on the front of the frame and a different software and user interface. It is technically a more advanced frame.
