subnotebook
A laptop computer that weighs less than four pounds. In order to reduce weight, subnotebooks, also called "ultraportables," often eliminate built-in CD/DVD drives, relying on external units to be plugged in when needed. However, if optical discs are required on the road, an external drive kept in the same travel bag as the computer generally results in more overall weight than a built-in drive would have added in the first place.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 Ultra-Mobile PC.
