it doesn't really affect me much. i'm just curious. so the 1st, 2nd, 3rd generation has the intel core duo chipset. with the 2nd and 3rd generation has the updated core duo chipset (core 2 duo) i know i'm right so far. so are these chips the Merom Chips? Now, the 4th generation Macbooks (the new one's just realeased) they have the Penryn Chip? <-- is this still core 2 duo technology? an updated version??? is this correct??
