The ThinkPad T and X Series laptops have been redesigned to give professionals the sleek, yet durable business machine the modern workforce is demanding. The MIL spec machines are enhanced with traditional rich stroke (1.8mm) keyboards that are spill proof. A higher level of security is provided by blocking the user-facing camera with a physical closure mechanism. These series reflect the latest technology while retaining ThinkPad DNA of being simple and reliable. ThinkPad T and X Series use high quality carbon fiber and magnesium alloy to achieve thinness while retaining the strength and durability required to be a ThinkPad. For RF connectivity, Magnesium alloy and glass fiber reinforces plastic to create an invisible “window.” Utilization of die-cast and CNC technology minimizes gaps, reducing the overall device size. The result is the perfect balance of portability and solid construction for the compact business laptop.
