The Sony Dash 'Mr. Sun' commercial references the same Mr. Sun we used to sing to as children during rainy days. Apparently, he is also a morning consultant.
The Sony Dash is a tablet device aiming to compete with the iPad. The Sony Dash 'Mr. Sun' commercial advises you to wake up to your Dash every morning, by having Mr. Sun advocating that Sony's new technology is going to be huge. I personally wouldn't hire Mr. Sun for advice--he seems to be quite the fire hazard.
