Notebooks, like Netbooks, are portable, but some are becoming increasingly less so (the 17-inchers) some more so (the ultra-thins), and users of notebooks tend to pack them away in bags with all sorts of accessories before moving anywhere beyond the office or home. Although a few notebooks are able to connect to the Internet via cellular networks as well as Wi-Fi, being “locked” to a carrier is not widely considered an advantage. Thus notebook users often invest in wireless modems that are external.
Interestingly, we may see netbooks that are sold by the cellular carriers themselves as a bundle of Internet service and the device. Consumers would be likely to consider an inexpensive netbook expendable and simply stop using the wireless connection when the cellular contract was up.
So netbooks are purpose-built for a limited role, while traditional notebooks are multi-purpose general tool. (Click the image from Intel to enlarge the graphicon that explains the uses of each.)
