Smallest (when folded) laptop portable stand/desk? (For Inspiron 700m)

Hi all, I’m the new owner of an Inspiron 700m. My lap tends to be very twitchy, so I’d like to buy a portable laptop stand/desk such as the one displayed here:

Ideally, I’d also like a little bit of room to the side for a mini mouse (given that this is an Inspiron 700m we’re talking about, this shouldn’t be too hard).

Do you have a recommendation for a teeny tiny stand (teeny tiny as defined by the size it becomes when it’s folded up)?

LapGenie. Using one now.

But it’s not like it sounds. It is just a stand for the PC.
