Portable PCs

Types and Classes of Portable Computers
Three basic form factors describe most of the PC-compatible portable computers on the market today:
laptops, notebooks, and subnotebooks. A fourth type, handheld/palmtops, is not currently being distributed
outside of Japan, but these are still useful if you can purchase a used model. The definitions
of the first three types are fluid, with the options available on some systems causing particular models
to ride the cusp of two categories. The categories are based primarily on size and weight, but these factors
have a natural relationship to the capabilities of the system because a larger case obviously can fit
more into it. These form factors are described in the following sections. Note that these designations
are somewhat vague, and the marketing departments in most companies like to come up with their
own terms for what they think a particular system might conform to. So don’t be surprised if you see
a system I might refer to as a

laptop be called a notebook, or vice versa, by the manufacturer.
