PSP modder jube808 has added a working touchscreen to his PSP, as part of his efforts to add features he feels Sony dropped the ball on with his beloved handheld. The on-screen keyboard looks pretty responsive, and can be used with fingers or a stylus. Such a mod is probably making PSP homebrewers salivate with PSP/DS hybrid potential. Another video has a closer look at the whole rig.
