Laptop Buying Guide
Forward - The purpose of this article is to provide you with
unbiased information for your laptop/notebook computer buying
decisions. We've tried to make this guide easy to read and
informative, however it also includes detailed technical information
for the more advanced reader.
This guide is divided into several different chapters which
include: what to consider before purchasing a laptop or notebook
computer, recommended laptop features, an explanation of laptop
video memory and how it effects screen resolution, a notebook
CPU speed index guide, details on the mobile CPUs that are
in the speed index, hints on buying a laptop, and a list of
other laptop/notebook computer resources.
The right menu bar contains a list of the different chapters
that you can use to jump to the chapters you are most interested
in.
What to Consider Before Purchasing a Laptop Computer
1. Portability - The main reason to have a laptop or notebook
computer is portability - the need to take your entire computer
from one place to another. If you don't need portability,
then you should probably buy a desktop.
2. Expense - Laptop computers cost almost twice as much as
comparably equipped desktops. Shocking isn't it?
You can actually buy two comparably equipped desktops for
the price of one laptop. So if you have to have a computer
in two separate places, you would be better off with two desktops
(if they were reasonably close together you could hook them
together in a wired or wireless local area network (LAN).
3. Speed - Laptops are 20-30% slower than a desktop with
the same features (CPU, hard drive capacity, etc.). Slower
CPUs, motherboards, hard drives, and video systems all contribute
to the speed loss.
4. Upgradeability - Laptop computers are mostly non-upgradeable.
Whatever CPU, video card (built into the motherboard), sound
card (also built-in), and screen, that come with the laptop
are the same parts the laptop will end with.
While it is possible to upgrade main memory, and removable
drives, the upgrades can cost twice as much as a desktop's.
Upgrades using PC cards or docking stations are also very
expensive.
You can also upgrade newer laptops through their USB, USB
2.0, and Firewire ports. Only USB 2.0 and Firewire ports can
run high speed devices e.g. hard drives and DVD drives. Again,
all external drives cost almost twice as much as an internal
drive.
5. Serious Gaming. You will need to spend at least $2500 for
a laptop that can play current games at a respectable speed.
I don't recommend laptops for serious gaming no matter how
much you are willing to spend. Why?
Because if you love to play games, about 1-1.5 years after
you purchase your laptop you will find it isn't fast enough
to keep up with the latest new game. At that time, you will
regret buying a gaming laptop. However, if you have the money,
and want to throw down $2500 every year or so, more power
to you.
On the other hand, if your computer budget is limited, it's
better to have a functional laptop and spend your gaming dollars
on an upgradeable desktop.
Recommended Notebook Features
Memory, Memory, and more Memory - Most lower-priced notebooks
are sold with 128 MB of system memory (RAM). That's not enough
for running applications efficiently under Windows 95, Windows
98, Windows Me, Windows 2000, and Windows XP. If you use your
notebook for occasional typing and web browsing you could
get by with 128 MB of RAM but you would probably be much happier
with 256 MBs. Power users should try to get a notebook with
at least 512 MB or more. It is very important that the memory
is purchased when you buy the computer as many notebooks have
only one or two memory expansion slots and you will wind up
throwing away the old memory when you upgrade.

you can save about half the cost of a memory upgrade when
you buy your memory direct from Crucial.com instead of buying
from the notebook manufacturer.
Batteries - Lithium batteries are superior to other kinds.
Hard Drives - 20 GB minimum. Of course, larger is better.
Hardware DVD/MPEG-2 - All DVD drives rely on MPEG graphics
compression to display video. The current standard is known
as MPEG-2. MPEG-2 compression can be provided by software
(slow) or by hardware (fast).
It is generally agreed that a 500 MHz or faster Pentium III
or Athlon is required to play software DVD effectively. Needless
to say, hardware MPEG-2 is more desirable, and will provide
smoother playback. Hardware MPEG-2 is a video chip function
in notebooks.
Video Screens - There are basically two kinds: active matrix
(TFT) and dual scan (STN)/passive matrix screens. Another
type of passive matrix screen is called HPA (High Performance
Addressing). HPA screens are generally brighter than plain
dual scan screens.
Active matrix screens are faster, brighter, and cost about
$200-$300 more than a dual scan/HPA screen. It's best to view
the screen before purchase to see if you like it.
Video Memory and Screen Resolution - The screen resolution
of any notebook or desktop computer is a function of the graphics
adapter, amount of Video RAM available, the size (pixel density)
of the screen shown (e.g. 640x480), and the number of colors
used. These screen features are loosely defined by the type
of output the screen can produce e.g. VGA, SVGA, XGA, and
SXGA as shown in the table on the next page.
