Laptop Thoughts: Laptop Bag Includes Built in Table

"It's called the Laptop Table Bag and it looks like a surprisingly normal, if decidedly corporate-issue, laptop bag. But, out of the bottom pivots four legs to hold your mobile device at what may or may not be a comfortable height. The 5980 yen ($75) contraption weighs about six pounds empty."

At first I thought this was cool, but then as I thought about it, not so much. How often do you find yourself without a table or other suitable surface to set up your laptop on, yet you have the space/time to set something like this up?
