Is a Slate (UMPC) More Social Than a Convertible Tablet PC?

Loren Heiny raises the question in the title of the post based on an experience sharing pictures with friends. For a number of reasons he believes he is much more likely to pass around a UMPC or slate than a convertible Tablet PC or cellphone/pda.

In fact, I think if I’d performed the same queries on my M400 Tablet PC, I bet I’d simply have swiveled the screen around and expected everyone to hudle around to see the screen.

Instead, with the UMPC it was small enough that I could pass it around. Was that a good thing I began to wonder? Did the act of “sharing” the physical device make it more social? More friendly if you will?
