This may not be such a great idea. I can't imagine why I would want this. I'm with you on this one. I can't see a compelling reason for it.
Some of the technology out their baffles me as to why it exists. This would be one example. Another one would be my cell phone .. it has a camera in it. Because of this, it is twice as big as it should be and when it's in my pocket it looks like I overdosed on viagra. I hate it!! I don't want a camera in my phone, if I wanted to take pictures I'd buy a camera!!
