Netbooks are a new emerging category of Personal Computers. There have been several efforts over the years for a low-cost and compact mobile PC. The introduction of the Intel Atom microprocessor in 2008 spurred the growth of netbooks, reaching 12.5 million units in 2008.
The key feature for a netbook is that it is designed primarily for web browsing and emailing. Thus, wireless connectivity to the Internet is necessary. Low-power consumption, compact design and light weight are essential.
