Though Samsung is No. 6 on the best-selling notebook brand list, the company boasts the No. 1 best-selling notebook over all for the month of April: the 11.6-inch Chromebook. The Chromebook has a 1.7GHz Samsung Exynos 5 dual-core processor and holds over six hours of battery life. As eight of the 10 brands found on this list sunk in dollar share from the previous April, Samsung improved a full 5.7 dollar shares.
