A low-cost Craig netbook with Android. Netbook is a generic name given to a category of small, lightweight, legacy-free, and inexpensive laptop computers that were introduced in 2007. Often significantly less expensive than other laptops, by mid-2009, netbooks began to be offered by some wireless data carriers to their users “free of charge”, with an extended service contract purchase. In the short period since their appearance, netbooks grew in size and features, and converged with smaller, lighter laptops and subnotebooks. Many major netbook producing companies stopped producing them by the end of 2012. Many netbook products were replaced on the market by Chromebooks, a variation on the network computer concept in the form of a netbook.
