Hi - I recently got my parents to switch from their windoze computers to a new 20 inch 2.0ghz imac. They purchased this computer 3 weeks ago. My question is this, seeing that the imac has just been updated to 2.1ghz and the isight etc. Are they eligible for this computer for free in exchange for the imac they just purchased because it falls within the 30 day purchase plan apple has regarding hardware updates? Any help would be greatly appreciated. Thanks!
