ThinkPad Ultrabook X Series Intel Core i7-3667U 4GB Memory 256 GB SSD Intel HD Graphics 4000 14.0" Windows 7 Professional 64-Bit X1 Carbon(344425U)

Some ultrabooks are composed of plastic, which can provide greater comfort while typing. Others are built with aluminum frames to protect the computers, but aren't often comfortable to use. Lenovo ThinkPad X1 Carbon notebooks are made from carbon fiber, which offers durability without rigidity. The material does not add much heft to the computers, as they weigh only 3 pounds.

These ultrabooks also have software for improved video conferencing. Single-user and multiple-voice modes are available, meaning that internal microphones are optimized to pick up every sound. The microphones also won't broadcast audio feedback from keyboards due to noise suppression software. Additionally, the 720p webcam produces image quality during web conferences that matches the ThinkPad's sound clarity.
