After almost 5 years, my AirPort Express finally died [802.11g], and now I'm in need of a new one. I was thinking of upgrading to the AP Extreme, for the wireless file sharing capabilities using an external HDDs. One of the complaints people had about the extreme was that the external HDD thats connected is always spinning 24/7. I like that when I connect a hardrive to my Mac, it goes to sleep when I'm not using it. I wouldn't want my HDD spinning all the time and its unnecessary wear and tear on the HDD as well as unfriendly to the environment. So does anyone know if Apple has resolved this issue? Thanks.
