Bluelounge has come out with an ingenious way of adding flexibility to MacBook Pro users using an adhesive-backed flip-out kickstand leg it calls the Kickflip. When adhered to the bottom of either a 13-inch or a 15-inch MacBook Pro using a strong yet removable and reusable adhesive, forms a kickstand which puts your Mac at an elevated typing and viewing angle much like the small flip-out legs behind most keyboards.
The Kickflip is a relatively thin rubberized piece of plastic with a hinge mechanism that sticks to the bottom side of the laptop and stays flat until you flip it out to its standing position when you need elevated support making it slightly more comfortable and ergonomic to type on the keyboard. You can get Bluelounge's Kickflip right now for $18, and in two different sizes that fit the 13-inch or the 15-inch MacBook Pro (Retina and non-Retina models). Unfortunately, the Kickflip MacBook Air or other laptop models.
