Netbooks are a popular, cheaper alternative to full size notebook and desktop computers. While some netbooks ship with Linux, most consumers are opting for Windows XP-based netbooks. What makes a netbook different from a notebook or desktop computer? The primary difference is size – netbooks fall somewhere between the smallest notebook computers and a large smartphone. Netbooks are also less powerful PCs – to reduce the cost. As a result most netbooks can’t run Windows Vista and ship with Windows XP (and in a few cases Linux). To save even more money some consumers install OpenOffice instead of Microsoft Office. Netbooks are available from many manufacturers including Acer, Asus, HP, MSI, Dell, OLPC (One Laptop Per Child), Medion, Kohjinsha, Lenovo, Toshiba and others.
