Digital Photo Frames

What's the point in a digital photo frames? When I saw them being released onto the market I couldn't understand the purpose and just worried about the electricity being used. I mean, with real photos they just sit there doing nothing. They don't consume electricity and kill the planet. They are also pretty expensive and of course people are just puting it on their credit cards. It's no wonder that so many people are having to take out payday loans and such like. It's just stupid. I wish that people wouldn't buy technology just because it's there. Has it really improved people's lives? My friend has a few for displaying Cebu photography which are really nice but don't think they really need to be in a digital frame.
