The Transformer Book T300 Chi rocks an all-aluminium unibody design with diamond-cut chamfered edges for a well-built chassis. The tablet / keyboard is held together by a neodynium magnetic hinge, so no hardware connections to worry about. The keyboard is a standalone bluetooth device, with it’s own battery pack. The battery cannot be shared so you would need to charge them separately but the keyboard should be good for a week’s use.
The Transformer Book T300 Chi compares favourably with the Surface Pro 3. In fact, the T300 Chi tablet itself is actually lighter than the Surface Pro 3, (0.72g vs 0.80g). The keyboard is heavier though, as Asus opt to implement a more traditional keyboard experience, which might be more favourable to heavy typists. When docked, the Transformer Book T300 Chi weighs 1.44kg, and is 16.5 mm thick. A whisper thinner than the Macbook Air at 17mm.
