Just a note about PSP screen protectors : they are the correct size, but as the PSP doesn't have a touchscreen, not always the correct thickness. I bought a pack (of admittedly very el-cheapo ones) that were so thick that the touchscreen digitizer didn't respond at all any more. I ended up reusing them for a lot of other stuff (like my mp3 and camera screens) but also bought a Brando specifically made for the 770 :-)
