Which Laptop to buy?
What to Consider Before Buying a Laptop
The first and most important question facing you as a laptop buyer is what you will be doing
with it. Are you the type of computer user who uses it (only reluctantly) to check your email
and pay the bills online? In that case you probably don’t need an expensive gaming rig with
all the add-ons and the fastest graphics card. Save your money for a budget machine that
lets you do all those things just as efficiently.
PC or Mac?
Apple is doing a better job than ever in stealing users from Microsoft Windows to their
proprietary Mac platform. Windows Vista on the other hand has received a lot of bad press
since its launch. Does that mean everyone should get a Mac? Not really, but it makes sense
to at the very least consider and compare the Mac when shopping for a new laptop.
Since Apple switched to Intel processors, Mac hardware will run Windows just as easily as it
runs Apple’s OS X. Then again, most consumers buy a MacBook for the sake of using
Apple’s operating system OS X, which is currently at version 10.5 ”Leopard.” It’s a very
stable, nice-looking, and easy to use operating system, but its software base is not as large
as the PC’s. This means that finding free program for this or that purpose is a lot harder for
Mac users than it is for Windows users.
At the same time, many of the arguments against Windows Vista are exaggerated. Vista is
not a “bad” operating system or necessarily problematic. But it does consume more
resources than its predecessor XP and requires a more powerful PC to provide a pleasant
experience.
Moreover, the fact remains that you have to pay a little bit more for equivalent hardware
when you buy a Mac. Although Apple fans would probably argue that it’s worth the premium
thanks to the excellent build quality of the Mac, and of course to get to use OS X.
With the respective companies’ new operating systems on the way – Microsoft’s Windows 7
and Apple’s OS X "Snow Leopard" – the Mac vs. PC battle won’t be over any time soon.
The choice ultimately boils down to personal preference. If you are inexperienced with both
Vista and Leopard, read up on the differences and try them both out to find out which suits
you best.
Key Components in a Laptop
Smaller and less power-hungry components are used in laptops,
to make them run cooler and more efficiently than desktop PCs.
Other than portability, you will get less noise and heat with a
laptop, the downside is that the components are slightly more
expensive and less powerful. It can also be difficult or even
impossible to upgrade later on, so it’s best to choose carefully
right from the start. In case you are not that savvy with
computers, here are the key parts of the laptop that have the biggest effect on price and
performance:
CPU/Processor
The Central Processing Unit – also known as the CPU or just
processor – is the core and "brain" of the computer. This is
where all of the essential calculations take place, and therefore
it has a significant effect on almost everything you do on the
computer.
Its speed is measured in MHz or GHz (1000MHz). This
number determines with how fast the processor handles
instructions in cycles per second. Not all GHz’s are created
equal, however. Newer generations or different processor models can handle various amounts of instructions per cycle. Another important aspect of the CPU is its number of cores. Basically, one core equals one processor, so a dual-core processor can (at least theoretically) process twice as much data.
Intel is currently leading the processor competition, with AMD a distant second. Both
companies offer powerful and dependable processors, but Intel has the performance lead for
now while AMD caters to the lower-end market. Measured in both MHz and power
consumption, Intel processors are also more efficient, but for everyday use this shouldn’t be
too noticeable.
The processor is usually the component with the most noticeable effect on both the laptop’s
performance and the price tag, and you can’t upgrade it later, so choose wisely. Most
processors today lie in the range 1.6GHz to 2.5GHz, and prices vary accordingly. Generally
speaking, you will get the most performance for your money at CPU speeds around 2.0GHz.
RAM Memory
RAM stands for Random Access Memory. As opposed to the
hard drive, which stores your data, RAM is where your data
resides while you’re actually using it. Some tasks require huge
amounts of RAM, like photo and video editing, but having lots
of applications open at the same time (multitasking) while
running others in the background will also eat lots of RAM.
When you are out of available memory, the computer starts swapping memory with the hard drive, which can slow down any system considerably. Basically, the more RAM you have, the
better, and memory modules are very affordable at the moment so getting some extra RAM
is definitely a good investment.
The bare minimum for running Windows Vista is 512MB, but more is definitely
recommended. Try to get a laptop with at least 1GB and preferably 2GB for a smooth Vista
experience. If you run XP or Mac OS X you can get away with less, but it’s always a good
thing to have lots of RAM, especially if you plan to edit photos or videos, or work with lots of
active windows at a time.
Hard Drive
There are two types of storage devices for your laptop –
the conventional hard drive with spinning platters, and the Solid State Drive (SSD). SSDs are much faster, completely silent, and consume less power than traditional hard drives. Unfortunately, they are also
much more expensive, especially when compared as cost per GB. Consequently most laptops are still equipped with old-fashioned hard drives. If you plan to use the laptop to store a lot of videos, photos and music, look for as large a hard drive as possible (measured in GBs). However, this is one component that you actually can upgrade, so it’s not a disaster if it gets full – you can always upgrade or use an external drive. If you’ll only use it for work and store documents and spreadsheets, you won’t need lots of storage – also consider an SSD in this case.
Graphics Card The graphics card, or GPU, is the single most
important component if you want to play any modern games. There
are different types of graphics: integrated or dedicated, and if you want gaming performance it’s absolutely crucial that you get a laptop with dedicated graphics from either ATI or Nvidia. Integrated Intel graphics are more common, but can barely be used for anything that runs in 3D. Powerful graphics cards generate a lot of heat and use lots of current, and for that reason you’ll only find them in larger, desktop replacement-type laptops. If you plan on using your laptop for regular office work, you may actually be better off without dedicated graphics. Otherwise, look for the latest Nvidia or ATI chip for gaming ability.
Choosing the Right Size
When you go comparison shopping for laptops of different sizes, you’ll notice that prices tend
to go up as sizes go down (with net books being a notable exception). The most common size
is around 15 inches. A 14 to 15-inch laptop is usually a reasonable compromise between
portability and performance. Smaller, ultra portable laptops are fitted with more expensive and
less powerful low voltage processors, which are excellent for having a long battery life when
traveling, but less suited for more demanding tasks like games.
Mainstream/Desktop Replacement Laptops
Most laptops fall into this category; 14, and 15 inches or larger with standard components.
The screen is large enough to work in front of for longer periods, while you retain the
portability aspect (if it’s not much larger than 15 inches). These laptops can be designed for
almost any task – business use, home entertainment or gaming – and are available in all
price categories. Bigger desktop replacement laptops allow for even more performance, on
par with most desktop PCs.
Ultra portable
Lightweight, thin and ultra portable laptops (excluding net books) are designed for mobility
from the ground up. Screen sizes range from 11” to 13” and the components are custom
made to reduce weight and prolong battery life.
Net books
Net books are a category of their own in several ways. It’s a relatively new phenomenon,
originally inspired by the OLPC (One Laptop per Child) initiative and later by the computer
manufacturer ASUS’ extremely popular EEE PC series. By netbooks we refer to small, 7” to
10” laptops with less powerful hardware, intended for light usage such as web surfing and
simple office tasks.
Most netbooks are built on Intel’s Atom – a single-core, small form factor processor with low
power draw and less computing power than regular laptop processors. Having only a
netbook might be sufficient for some, but it’s good to know that they are not even remotely
capable of more strenuous tasks like gaming or high definition video playback. Not yet, at
least.
Gaming
Dedicated gaming laptops are usually quite large and heavy, with a 17” or even larger
screen. If you can settle for a graphics card that isn’t the fastest, you might be able to find
some smaller variants too that provide enough power for light gaming.
Laptop Reviews and Comparisons Online
Buying a new laptop is a big deal for most people, and it makes sense to read up on opinions
from both professionals and other users before you buy. Once you have an idea of what to
look for, visit laptop review sites online – there are several good, unbiased websites that are
not afraid to warn you off bad products.
Monitor section on price comparison sites such PriceGrabber.
Traditional computer magazines like PC Magazine and Laptop Magazine have extensive
review databases on their respective websites, but dedicated laptop sites have even more to
offer.
The most popular and reputable sites to visit when looking for laptop reviews include
laptoplogic.com, laptopical.com, notebookreview.com, and cnet.com
Best Places to Buy a Laptop
When it comes to actually purchasing the laptop, you will get great help from comparison
shopping websites (unless it's a Mac laptop). Besides price comparison sites, you should
also be able to find customer reviews and comments on different online retailers. What kind
of support to expect after purchasing a laptop is possibly as important as the price.
The most popular places to visit for comparison shopping are pricegrabber.com and
bizrate.com.
