We have a user here that has one of the originals. If I remember reading the materials on the original, you were NOT supposed to use a laptop resting on the unit. The heat coming out of the bottom of a laptop could damage the unit. That's probably when they changed the form factor was to prevent people from using it exactly the way you've described. The original was designed with that form factor to easily slide into a laptop bag, not sit under the laptop while in use.
I have a Trager Cross Country Laptop Bag. It can alternate between a bag you can swing on your shoulder and a backpack. I've been carrying mine for over two years now and love it. You can do a search for Trager at ebags.com and pick one up for about $100.
