Now there are closeup pictures that provide us with a little more information, and a much better look.
The volume rocker is at the top of one side, next to what is most likely a mute switch or screen rotation lock. We can also see that the headphone jack is on the upper left side of the device.
The 7" tablet from Dell is rumored to be the Dell Looking Glass, but Dell failed to mention a name. He is just teasing us, perhaps to avoid taking the thunder out of the Dell Streak.
Enjoy the pictures, and the video of the presentation thereafter (the tablet appears at about 1:30).
