Digital Clock with Digital Picture frame

when someone recommend me a digital gadget just liked upper mentioned digital clock with built-in frame. what concerned me mostly is how long the full charged battery inside.In this case, the Battery can obviously decide its value as a smart gadget we take to office. Ideally, I’d like my clock stand on my desk 9 hours a day without charge by USB or power cord which will make my desk in a terrible mess.

I ,a breif while ago,got my first&impressed 2.4 inch digital frame from a website called http://www.udiggit.com as a xmas gift to my wife. She loved it so much as it features some latest function such as google calender, yahoo weather report. however, the battery can only last with 4 hours. who will care about the battery when those fresh & innovative features rush into your life.
