Netbook
Netbooks (sometimes also called mini notebooks or ultraportables) are a branch of subnotebooks, a rapidly evolving category of small, lightweight, and inexpensive laptop computers suited for general computing and accessing Web-based applications; they are often marketed as "companion devices", i.e., to augment a user's other computer access.___________________
At their inception in late 2007 — as smaller notebooks optimized for low weight and low cost[2] — netbooks omitted certain features (e.g., the optical drive), 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" screen diagonal[3] to over 10.1". A typical weight is 1 kg (2-3 pounds).
Often significantly less expensive than other laptops, by mid-2009, some wireless data carriers began to offer netbooks to users "free of charge", with an extended service contract purchase.___________________
In the short period since their appearance, netbooks have grown in size and features, now converging with new smaller, lighter notebooks. By August 2009, when comparing a Dell netbook to a Dell notebook, CNET called netbooks "nothing more than smaller, cheaper notebooks," noting, "the specs are so similar that the average shopper would likely be confused as to why one is better than the other," and "the only conclusion is that there really is no distinction between the devices."
However, in the same month, Walt Mossberg called them a "relatively new category of small, light, minimalist, and cheap laptops."
