subnotebook

A laptop computer that weighs less than four pounds. In order to reduce weight, subnotebooks, also called "Ultrabooks" or "ultralights," often eliminate built-in CD/DVD drives. However, if optical discs are required when traveling, an external drive in the travel bag generally adds more weight than a built-in drive.

The Mini Laptop/Netbook
In the 2007 time frame, subnotebooks called "mini laptops" and "netbooks" made their debut, the latter term coined by Intel for machines that use its Atom processor. Weighing up to three pounds, mini laptops/netbooks have screens from 8 to 10" (see netbook). For features of portable computers, see laptop. See ultrathin laptop, notebook and Ultrabook.


The Trend Setter
In 1998, Sony popularized the subnotebook class with its VAIO (pronounced "vy-o") 505G at three pounds and less than an inch thick. To reduce traveling weight, floppy and CD-ROM drives were external, and a docking station was included. (Image courtesy of Sony Corporation.)
