Small Is Big in Notebooks--but Not Too Small

Ultralight computers add back a few more ounces and a lot more usability

3 min read

A lot of road warriors have learned, much to their chagrin, that a notebook computer can indeed be too light or too thin. Shrink one much below 1.8 kilograms (4 pounds)—the class known as ultralight—and it gets maddeningly hard to use for much more than e-mail or Web browsing.

That’s why manufacturers have recently begun reemphasizing a slightly larger breed—call them notâ''quite-ultralights. These machines sport displays of at least 13 inches; fuller, if not full-size, keyboards; built-in optical drives; Ethernet and other ports; and more processing power than their rail-thin predecessors.

It’s hard to learn, but your code will produce fewer nasty surprises

You’d expectthe longest and most costly phase in the lifecycle of a software product to be the initial development of the system, when all those great features are first imagined and then created. In fact, the hardest part comes later, during the maintenance phase. That’s when programmers pay the price for the shortcuts they took during development.

So why did they take shortcuts? Maybe they didn’t realize that they were cutting any corners. Only when their code was deployed and exercised by a lot of users did its hidden flaws come to light. And maybe the developers were rushed. Time-to-market pressures would almost guarantee that their software will contain more bugs than it would otherwise.
