Netbooks from WikiPedia:

Netbooks (sometimes referred to as mini notebooks or subnotebooks) are a rapidly evolving category of small, light and inexpensive laptop computers suited for general computing and accessing web-based applications; they are often marketed as "companion devices," that is, to augment a user's other computer access. Walt Mossberg called them a "relatively new category of small, light, minimalist and cheap laptops." By August 2009, CNET called netbooks "nothing more than smaller, cheaper notebooks."

At their inception in late 2007 — as smaller notebooks optimized for low weight and low cost — netbooks omitted key features (e.g., the optical drive or ethernet port), featured smaller screens and keyboards, and offered reduced specification and computing power. Over the course of their evolution, netbooks have ranged in size from below 5 inches to over 13, and from 2 to 3 pounds (~1 kg). Often significantly less expensive than other laptops, by mid-2009, netbooks had been offered to users "free of charge", with an extended service contract purchase.
