While the stand folds down, its definition of portable may not be the same as yours. The stand weighs 1.9 pounds, and its desktop footprint is 10.5x14 inches, with a folded thickness of 1.25 inches. That means you're going to need a pretty big shoulder bag to carry this around with you. Still, finding a laptop stand that works well for larger laptops is rare. That's a shame, as big, bulky 17-inch desktop-replacement laptops that stay rooted in one place very often can benefit from a more ergonomic angle (and extra cooling help). I found a 15-inch laptop matched up almost exactly with the edges of the stand, so a 17-inch desktop replacement will spill over a bit, but not enough to be unstable.
The design is inoffensive but forgettable. Light-gray plastic is offset by dark-gray gabardine padding that covers almost the entire bottom surface, and forms a padded border around the fan grate on the top surface. A USB cable, to power the dual fans inside the stand, sticks out from the left side, but can be tucked inside to stay out of the way.
