A smartbook was a class of mobile device that combined certain features of both a smartphone and netbook computer, produced between 2009 and 2010.Smartbooks were advertised with features such as always on, all-day battery life, 3G, or Wi-Fi connectivity and GPS (all typically found in smartphones) in a laptop or tablet-style body with a screen size of 5 to 10 inches and a physical or soft touchscreen keyboard.A German company sold laptops under the brand Smartbook and held a trademark for the word in many countries (not including some big markets like United States, China, Japan, or India).
