PC World: "The term netbook, coined by Intel, conveys little useful information about this category of machines. Sure, they all have wireless networking, but so does every other laptop. What the term originally helped to identify was a class of small, ultralightweight, cheap-as-dirt mobile PCs.
Netbooks are tiny--usually between half and two-thirds the size of a garden-variety laptop--and they typically weigh around 2.5 pounds. With their cool, slim designs, they outclass some fancy ultraportables. And best of all, these diminutive laptops start at around $200 (in some cases $100, when purchased as part of a mobile broadband promotional deal)."
