I was looking at these, but the lack of a battery backup makes it a no go as an alarm clock.

But, I have to say that I've been intrigued by it. It's sort of like my old n800, a "jack of all trades and master of none" device whose concept just seems to befuddle most people. However, there is a rumor that Sony will refresh the line soon, including a model with a battery backup. (Could be why we are seeing the Dash at really deep discounts lately.)
