Very convenient to use the tablet PC chair / sofa and bed (and even on a desk). Triple interest for this article - The PC and thus more heat is quieter. The table allows for a customized adjustment of the tilt according to his own vision comfort in reading texts and videos. Good stability (in my case for a 42 cm CP) - Small problem though: while sitting on chair / couch, large stature people will be limited in the tablet folding positions and may have amounts of the tablet resting on the thighs. It would be appropriate that the table is wider (or width adjustable).
