Samsung as part of events on Tuesday brought a new notebook line to the US. Both take some, though not all, of their cues from Apple's MacBook Pro, including an oversized, 'buttonless' trackpad (here run by Elan and not Synaptics), illuminated chiclet keys, and aluminum across most of the body. Space efficiency is key, Samsung says: a 15.6-inch model can comfortably fit a numeric keypad, while the '13-inch' version has a 14-inch display and uses an extra-thin bezel to fit into the smaller display frame.
