Im heading to the US at the end of the year and was thinking about buying a new MacBook Pro while over there, seen as the prices here (in Australia) are outrageously high (they are AU$550 cheaper in the usa for the exact same machine!!). Obviously the drives used in those machines will be NTSC so being able to convert it will dictate if ill be able to possibly buy one. So does anyone know if it can be changed to PAL permanently or even temporarily? Or any other possible problems i might have? much appreciated! cheers.
