The $499 Samsung model comes with a free 100 MB per month of 3G mobile data from Verizon — a fairly paltry number, but one that should allow users to accomplish minor tasks when they can't access Wi-Fi. Beyond that, there'll be a pay-as-you-go 3G service. There's also a $429 Wi-Fi-only model. Both Samsung notebooks feature a 12.1-inch display, Intel Atom processor (1.66GHz, according to PC World), a full-sized keyboard and an oversized clickable touchpad. The Acer model has an 11.6-inch display and weighs slightly less, at 2.95 pounds compared to Samsung's 3.26. They both have the regular SD card slots, USB ports (for cameras and storage), speakers, and headphone jacks.
