Recently, I've found that using my PSP to read or watch movies in bed at night is always uncomfortable in terms of posture. Using a stand might help; the stand that comes with the PSP is nice-looking, but it loses balance when placed on the bed.
Therefore, I decided to make my own "all-terrain PSP stand" (it seems like a Logitech box would work, but unfortunately, I don't have one).
First, take a piece of cardboard; I used the one from the motherboard box. Cut it into an appropriate size. (I recommend taping the edges after cutting to prevent future wear and tear. Since I didn’t do that, I had to fold it differently.)
