Round 4: The I/O Ports
Apple: I can count the number of ports on three fingers. You can guess which ones they are. You get a single USB port, a mini-DisplayPort, and a headphone jack. That's it.
Dell: Here’s where the big "D" gets it right. The Adamo has two USB ports, Ethernet and headphone jacks, one eSATA connector, one DisplayPort, and a user-accessible SIM-card slot for WWAN service.
Winner: Dell. As if this one was even going to be close. At least both machines offer Webcams and built-in microphones.
