5. Panasonic Toughbook F9
The Toughbook has long occupied a beloved niche among PC buyers thanks to its extreme durability and survivability from drops, spills, and other physical harm. Even with its built-in handle, the F9 weighs just 3.6 pounds, yet sports a 14.1-inch screen.
The F9 does compromise on performance, however, with a 2.4GHz Core i5 processor, 2GB of RAM (upgradable to 6GB), and a 320GB hard drive, though it also includes a rewritable DVD drive. Ports are likewise basic: one VGA, three USB 2, and one Ethernet -- plus a rarity today: a modem port.
