- Earphone socket: when the earphones are plugged in, it becomes uncomfortable to the left hand. The should’ve placed it in middle of the bottom part, parallel with the USB socket.

- Analog nub: not that it’s placed too low as many complain, but that it’s too flat and gets slippery when thumb gets sweaty.

- Square button: very loose in my PSP. Worse, it produces annoying creaking sound on pressing. That was a dumb move from Sony; to not elongate the system a couple of mms to get away from the screen bezel. Very dumb.

Other than these, the PSP is perfect.
However, I seriously think of visiting Sony’s repair office to check that square button. Very annoying to me.
