Description

FIELD OF THE INVENTION

The present invention relates to portable holders for computer laptops.

BACKGROUND

Laptops are a ubiquitous part of society and are used in virtually all aspects of the economy. People use laptops at their desk, on their lap while flying, on a train, in a car, while in bed, on a couch, even on a toilet. Use of laptops while standing and moving around, however, has largely been limited to balancing on one forearm, and typing single handedly with the free arm. Work-arounds have been made, most notably the Tablet™ PC which allows use of a stylus on a screen that folds on top of the laptop keyboard.
Presently known art does not sufficiently address and solve these problems. The following represents a list of known related art:
