It� not as sexy as the MacBook Air, but the X300 delivers all the features you would expect from a ThinkPad (and then some) in a 3-pound package.
At a mere 2.9 pounds with a 3-cell battery (and the swappable bay empty) and 3.3 pounds with a 6-cell battery (and a DVD burner in the bay), the X300 is also lighter than its footprint would lead you to believe. And we�e happy to see Lenovo went with a diminutive power brick (0.6 pounds); too often a hulking afterthought of a power adapter adds back the precious ounces engineers painstakingly shaved.
