On TV and in the movies, we see a lot of portable computers being used
in homes and offices. Does that mean that's the trend? Is that what you
should get?
Portable computers cost more, so unless you really have the need for
one, you get a lot more computer for your money with a regular desktop
PC. The main thing is portability. If you need a portable computer, get
a laptop. ("Laptop," "portable," and "notebook" all refer to the same
thing, by the way). Otherwise, a desktop computer is a better buy, and
better ergonomically.
The Price Difference
You might wonder why laptops cost more than desktop computers with
comparable features and power. That is largely because it is more
expensive to manufacture laptops and their parts. For portable computer
components, factors such as compactness, the amount of heat they
generate, their weight, and power consumption are more important than
they are for desktops. Those factors add to their manufacturing costs.
Space Requirements
While laptops are certainly compact, a desktop computer with a flat
panel monitor can take up almost as little space. While called a
"desktop" computer, the computer itself is most often kept on the
floor. That leaves just the monitor, keyboard and mouse on the desk,
which is really very similar in footprint to a notebook computer.
A great way to further reduce the space taken up on the desktop
computer is get a keyboard drawer to hold the keyboard and mouse. That
way, they slide out of the way under the top of the desk when they
aren't needed.
Be Mindful of Ergonomics
Ergonomics is the science of designing and arranging things so that
people can interact with them more comfortably and safely. The basic
ergonomic principals for computer use tell us that, 1) the keyboard
should be as close to your lap level as possible (assuming you
touch-type), 2) the monitor should be about arm's length in front of
you, and 3) the top of the monitor should be at about your eye level.
Try achieving that with a laptop computer! Two words: im-possible.
It is obvious then, that a desktop computer is much better
ergonomically than a laptop is. For prolonged use, especially, you're
much better off with a desktop computer.
And Don't Forget Usability
Another aspect of ergonomics is usability. Because of size constraints,
laptops also are lower on the usability scale than desktop PCs are. For
one thing, laptop keyboards lack the separate groupings of the
different sets of keys with space between them. For another, there are
fewer keys on a laptop's keyboard, so some of them have to perform
double duty. On a standard keyboard, you don't have to deal with that.
Screen Resolution
Computer monitors -- the bulky ones, anyway -- can be set at different
resolutions. In other words, you can change the fineness of the image
on the screen. The range is typically 640x480 -- that is 640 pixel
across and 480 pixels up and down -- to 800x600, 1024x768, or even
higher. At 640x480, the icons and such appear quite large; at 1024x768,
they are substantially smaller. The most common resolutions today for
desktop computers are 800x600 and 1024x768.
Something They Don't Tell You
Laptop displays, on the other hand, have a fixed, or native,
resolution. You can change the setting, but then the images and text
don't look good. While people tend to think that bigger numbers are
better, a higher screen resolution may not work as well for you. It may
make everything too small to see comfortably.
Remember, the laptop's screen is smaller that a desktop's. While a
typical desktop computer screen is 17" or so a laptop's is usually in
the range of 12" to 15." That is a big difference. Make sure you can
see everything clearly before choosing a high-resolution laptop.
