Toshiba Dynabook gets a small dash of style from its textured lid and deck, but glossy sides give the laptop a premium feel overall. On the plus side, this is one of the rare laptops with a removable battery, a feature we're always pleased to find. Toshiba placed two USB 3.0 ports, an Ethernet jack,, a metallic, reinforced security lock slot and a headphone jack on the Dynabook's left side. Most business notebooks are built to survive challenging conditions, but not the Dynabook (or other Toshiba machines we've reviewed).However, the spill-resistant keyboard can protect the laptop from a little water. While many laptops come with security lock slots, Toshiba claims the reinforced slot was tested to withstand 55 pounds of force. So the lock might actually be tougher than the rest of the laptop.
