I am considering ordering a new mac from the online Apple store, but I'm kinda weary about how well they protect it from all the stacking and tumbeling that may happen during shipment. Is it safe? I've seen a few posts before about people who order their mac online and aren't satisfied when it arrives. One guy talked about how his iMac made "buzzing" noises and was missing screws. Also, I had one more question. It appears that I can use an AirPort base station as an all-in-one cable modem and wireless router. Can the smaller AirPort Express do the same thing?
