Clever software lets you control the cursor, even when NumberPad is activated.
The backlit keyboard lets you type effortlessly in dark environments like aircraft cabins.
Accidents happen, and ExpertBook B9 is ready for them: its spill-resistant keyboard can cope with up to 66cc of liquids without harm, so minor spillage can be easily drained, cleaned, and dried.
B9 is engineered to make the typing experience more comfortable and more accurate. With ErgoLift hinge, the keyboard automatically tilts to the most comfortable typing positions. It also has widely spaced, long-travel keys that give out responsive tactile feedback for more accurate typing.
