Tablet
computers are more than just go-to gadgets for tech lovers. They've matured
into a super-thin and light replacement for a laptop and for a growing number
of people, a tablet is the primary – and possibly only – computer. Tablet sales
have surpassed the former king of portable computing, the laptop, in the past
couple of years. They're lightweight, easy to use and highly portable, and
they're designed to easily handle common tasks such as:
·
web browsing
·
email
·
ebook reading
·
writing and editing documents
·
playing music and videos
·
games
·
GPS navigation
·
live information updates
·
VoIP calling
·
video calling, and more.
There's
a lot of hype about the different brands and models available, about the best
size and the various operating systems. So how do you make sure you buy the
right tablet for your needs? There's a lot to consider and it's not always
obvious from the box exactly what's on offer. But knowing what features you
want in your tablet before you buy could well save you money in the long run.
Is a tablet right for you?
Maybe
your heart's already set on a tablet, and if so, feel free to skip this bit. If
not, it's good to know there are other options similar to the tablet that you
may not have considered:
Ultrabook:
A serious challenger to the tablet, Ultrabooks are light, slimline laptops that
are relatively cheap. They're ultra-portable and designed to have excellent
battery life, but with the speed and features you'd expect from a full-sized
laptop, but also with extra security features built into the motherboard.
E-readers:
With the arrival of the tablet, e-readers are fighting back by gaining
capabilities to take them beyond mere ebooks. Leading the charge are Amazon's
Kindle Fire and the Nook Color, offering colour touchscreens and even a range
of general-purpose apps, further blurring the line between e-readers and
tablets.
Convertible
tablet: Also known as a two-in-one or hybrid laptop, it has the power and
performance of a laptop computer, with the convenience and versatility of a
touchscreen tablet via a removable or foldaway keyboard.
Android, Apple or
Microsoft?
The
most important consideration when you're choosing your tablet is the operating
system that will best suit your needs. The OS affects which content ecosystem
you're tied to – Google Play (Android), iTunes (Apple) or Windows (Microsoft).
Each has their own app store and though they might all have some of the same
apps, they're not interchangeable between platforms. So if you have an Android,
an Apple and a Windows device, you'd probably have to buy the same app three
times to run it on each platform.
Apple's
iOS was the pioneer of apps with iTunes and its App Store. Such heritage means
that a wide range of apps covering myriad interest categories – often available
for free or at low cost – exist for all iPad models. Apple boasts more than a
million apps in its App Store, with around half that number having
iPad-specific versions.
Google's
Android OS is the biggest challenger to Apple's iOS, with apps available
through Google Play and various branded online stores offered by tablet
manufacturers. Android allows more scope for customisation, so if you like to
fiddle and tweak your operating system it may be a better option. It's also
more highly targeted by viruses and other malware, which means if you use an
Android tablet it's highly recommended that you install antivirus software.
Android is available on a wide range of tablets from different manufacturers,
so you have a wide choice of hardware. Android OS 4.1 or later is preferable,
as this version has major improvements in architecture specifically for
tablets.
Microsoft,
relatively late to the market with its Surface tablets, has a big challenge
ahead to make up lost ground with its app store. The 12-inch Surface Pro models
and the newer, smaller (10.8-inch) Surface 3 models offer the full Windows 8.1
environment, so you can easily use existing Windows programs on these tablets
and they're upgradeable to Windows 10. The Windows RT operating system of the
original Surface and Surface 2 tablets only runs apps from the Windows app
store.
The
Amazon Kindle Fire uses a custom-modified version of the Android operating
system, called Fire OS.
What to look for:
Screen size
As
with laptops, screen size on tablets is measured diagonally from corner to
corner and usually expressed in inches. Tablets typically fall into three
categories: compact (5-inch to 8-inch), medium (over 8-inch to 11-inch) and
large (over 11-inch). A
compact tablet is especially portable, lighter and easier to carry, as well as
usually being cheaper.
Medium
and large tablets provide a bigger screen area that can be especially useful
for productivity apps, games and web browsing. Their larger size may mean they
have a longer battery life because they have space for a bigger battery, but
that's not always the case – all iPads, for example, are claimed to have a
10-hour battery life, regardless of size.
Screen resolution
Screens,
also called displays, generally range from 1024 x 600 pixels up to 2560 x 1600
pixels in resolution. Display resolution is expressed in pixels-per-inch (ppi)
and the higher the resolution the sharper text and images will appear. Higher
resolution screens also require faster processors to manipulate all those extra
pixels and consume more power, affecting the device's battery life.
When
Apple launched its breakthrough Retina display on the third-generation iPad, it
set the bar very high for competitors. The Retina display is so-called because
the resolution is so high that the eye can't distinguish individual pixels when
viewed from a normal distance.
The
iPad's 9.7-inch screen has a pixel density (resolution) of 264ppi (double that
of the non-Retina display iPad 2). The iPad mini (with Retina display) has an
even higher pixel density of 326ppi (double that of the original iPad mini),
which is the same as the Retina display iPhone. Theoretically,
this means that higher resolutions were unnecessary as the difference would be
unnoticeable. However, this hasn't stopped competitors from pursuing even
higher resolutions, now well over 400ppi.
Storage space
Think
carefully about how you'll use the tablet and what your storage needs will be
before you buy. Unlike with PCs, you won't be able to upgrade the amount of
storage you have in a tablet.Most
tablets vary in capacity from 16GB to 128GB. How much space you'll need depends
on how you intend to use the tablet. All tablets are fine for general use like
checking emails, browsing the web, and streaming videos and other content over
the internet, because that doesn't require much information to be actually stored
on the tablet itself.
If
you like to carry around your music, videos and lots of apps, however, storage
capacity on the tablet will be an important consideration. For light use, 16GB
may be enough, but remember that the tablet operating system and mandatory apps
will take up a decent amount of that space even before you put your own content
on it. For many people, 32GB is becoming the starting point, especially when
you consider that many games can now be more than 1GB in size.
Tip:
If your tablet has external connections like an SD card or USB slot (as many
Android and Windows tablets do), you can get away with less storage internally.
Extra storage can be added via a memory card, USB flash drive or even an
external hard drive. There are also wireless storage devices for tablets
without hardware connections, like the iPad.
Online
access
Most
tablets have Wi-Fi built in, and many offer a version that includes mobile
broadband – 3G or 4G – for data, but that means signing up for a separate plan.
The other option is a Wi-Fi only tablet. These can be used, as the name
suggests, over Wi-Fi connections, but also by using your smartphone as a mobile
hotspot (available on most recent models). However, a 4G tablet with its own
plan may be worthwhile if your phone plan is restricted to 3G.
Hardware connections
Although
connections are a major consideration for PCs and laptops, they're less so for
tablets, most of which use a combination of Wi-Fi, Bluetooth and apps for
storage and transfers. Apple tablets have little in the way of hardware
connections, though some devices can be added via adapters to the tablet's dock
port, or wirelessly by purpose-built devices. Android tablets generally offer
more variety in hardware connections, with a USB port, HDMI-out or memory card
slots for extra storage being common.
Tip:
You can usually connect a keyboard or monitor via Bluetooth if you don't have a
USB or HDMI plug.
Battery
life
Battery
life is important due to the ultra-portability of tablets. Ideally, they should
last a full day of normal use before you need to recharge.
Processing speed (GHz)
The
processing speed of your tablet, measured in gigahertz (GHz), isn't such an
important decision in your tablet choice as it is when choosing a desktop or
laptop computer. That's because there aren't so many processor options. iPad
models all have the same processor in each generation but with Android-based
tablets it's very difficult to compare speeds between models due to the
different processors used.
Have you considered a
convertible?
If
you're looking to do some computing on the go, the obvious first choices are
either a laptop or a tablet. But there's a third option that promises the best
of both worlds – the convertible laptop. Also known as a two-in-one or hybrid laptop,
this versatile combo computer looks like a laptop but instantly converts to
allow use as a keyboard-free touchscreen tablet.
But
is a two-in-one computer better? Do you get the best of both worlds or is it
more a case of "jack of all trades, master of none"? Tablets have the
notable advantage of portrait-viewing mode, which is great for reading books
and magazines in particular. They're also generally the thinnest and lightest
mobile computing solution.
A
laptop is stuck in landscape view only – but laptops are generally more
powerful, run all your desktop programs, and have the singular advantage of a
built-in hardware keyboard and trackpad.A
convertible laptop should have all of these advantages in one compact package,
as well as the ability to instantly switch from laptop to tablet mode. Find
out more in our test of convertible (hybrid) laptops.
Cost
Prices
for tablets range from below $150 to more than $2000 depending on size,
capacity and connectivity options. The convertibles we tested ranged in price
from under $500 to $1700.
