Global Chromebook shipments in 2014 are expected to reach only 4-5 million units mainly because cloud-based storage is not popular enough and 4G mobile access is not sufficiently available, according to Taiwan-based supply chain makers.

　　Hewlett-Packard (HP), Dell, Acer, Asustek Computer and Samsung Electronics have all been aggressively promoting their Chromebook products with some prices already reaching US$199, the sources noted.

　　The sources pointed out that Chromebooks were unable to reproduce the same sales phenomenon as netbooks because of the popularity of mobile devices.
