Is the PSP GPS Receiver really worth it? I wouldn't use it that much for its map skills, but I heard it can be used in some games(Metal Gear Solid Portable Ops ). How do you use it in these games. I am seriously thinking of buying one of these now and the TV Receiver down the track if it supports Australian Digital TV broadcast. Thanks in advance Another question- If I buy a Japanese one will it display Japanese text on my PSP or English?
