Do we know if the SGS3 will use MTP like the Gnex does for USB connection? I don't have a problem on my Win 7 machine at home, but I have a heck of a time with MTP on my work computer (Win XP). It's very sporadic with regard to when it does and does not work. I get a different result every time I plug it in.
It probably (definitely) won't dissuade me from upgrading to the SGS3, but I hope it doesn't use MTP.
