Laptops help keep you in touch
and able to access information you need quickly when it's used away from your desk. However, before you buy a notebook computer it's helpful to learn more about
how to set them up and use them properly, so you can choose the
right model and accessories for your needs.

. . . . Using notebook computers ergonomically is a challenge . . . .
These portable computers have not been designed to be a substitute
for a desk-based computer, but their popularity has resulted in them
being used that way for many consistent working hours.
It is important to know how to position your laptop computer,
for example on an ergonomic laptop desk with a wireless keyboard and mouse,
because the screen and keyboard areas are attached
which make proper ergonomic positioning and comfort difficult.
Information taken from UCLA and other studies are summarized below.
If you use your notebook computer for periods of several hours or more
 continually, as is typical  of desktop computers,
consider purchasing ergonomic accessories
such as a height and tilt adjustable laptop stand or laptop drawer .
