Just as the iPad 2 rules the tablet landscape despite promising competitors like the Asus Eee Pad Transformer, and the  MacBook Air remains the undefeated thinness champion over rivals such as the
Samsung Series 9 900X3A, on the desktop side of things, Apple’s iMac range exemplifies
the most stylish and slim all-in-one desktop line on the block.



This is hardly surprising, considering iMacs sport a slim,
sexy look that’s all solid, edgy aluminium and sleek black lines. It’s a design
that has been class-leading, if not without its flaws, since it was introduced
on the 20in iMac all the way back in 2007. Thankfully, since then internals and connectivity have been updated several times. We’re looking at the latest refresh, which brings Intel’s quad-core Sandy Bridge CPUs, Radeon
6000M-series graphics and Thunderbolt connectivity to the older, 2010 iMac. Join us as we find out
whether this makes for the ultimate all-in-one desktop machine.

On the outside, almost nothing has changed. The seamless front consists of the frameless screen, elegant
black bezel with matching Apple logo, and aluminium base section. The sides,
back and stand are sharp-edged, attractively curved aluminium, which looks



Using machine-cut aluminium, and a physical build Apple has had several generations to
perfect, it’s not surprising that build quality is superb. Even the screen is
protected by a layer of glass. Quite simply, it’s the best-built all-in-one PC
money can buy.



There are a few minor downsides though. Its sharp edges can
make the screen uncomfortable to hold, move or carry. More importantly, there’s
no height adjustment, as found on the recent HP TouchSmart 610, though at least there’s a generous amount of tilt and this
adjustment is effortless.

The glass front, while very attractive, is also ridiculously
reflective. Thus, in an environment with a lot of ambient light it can be next
to impossible to make out dark material on the screen. However, if these
niggles don’t bother you, the iMac is still the most elegant and streamlined
all-in-one (AIO) around.

Along with the upgraded internals, connectivity is another
area where things have taken a significant step forward. Along the right edge,
Apple has incorporated the usual memory card reader and slot-loading DVD-rewriter.
The card reader takes SDXC, so it’s well up to the latest standard. However, for
those hoping that – this time around – they would finally get in on the
high-definition movie action with a Blu-ray drive, dream on.


Frankly, this is one of the iMac’s major remaining failings.
After all, it’s all very well for Steve Jobs to decide Apple users don’t need
or want Blu-ray in their machines, but we’re sure there are quite a few who
disagree – especially since its IPS-panel screen makes for nicer viewing than
most rivals (excepting the aforementioned HP TouchSmart 610, which also uses IPS).

At the back, there are 3.5mm headphone and microphone jacks
(doing double duty as optical digital audio in and out), four USB 2.0 ports, a
FireWire connector, Gigabit Ethernet jack and that magical
Thunderbolt port, here in the shape of a mini DisplayPort connector. Thunderbolt (formerly known as Light
Peak) can use a connector
that’s physically identical to that of this graphics standard, but in addition
to DisplayPort’s impressive video capabilities it also gives you an independent
data link, making it a USB 3.0 alternative.


For more on USB 3.0, read our article: What is USB 3.0 and do you want it?. The advantage to Thunderbolt is that it
offers a whopping 10Gb/s bi-directional transfer rate, but USB 3.0 is – for now
and the near future – far more prevalent, and backwards compatible with USB
2.0. However, for the first time since FireWire’s glory days, we can now
finally say that Apple offers a fast connectivity standard for external
storage, even if there are very few compatible devices as yet.

On the wireless front, we’re given both Wi-Fi N and Bluetooth
2.1 EDR.


The screen is a 21.5in affair with the Full
HD (1,920 x 1,080) resolution you would expect from this size, giving you
plenty of desktop real estate and letting you watch 1080p videos in all their
detail. It features the almost-flawless viewing angles, accurate colours and
decent contrast an IPS panel provides, making for an excellent overall viewing
experience if you can get past the reflective glass layer. However, the
competition is catching up here, with the TouchSmart 610 once again providing
an apt comparison with its larger, 23in IPS panel.


If you want more resolution and an even larger screen,
Apple’s 27in iMac remains unmatched. Essentially the Apple Cinema Display 27in with a computer built-in, its 2,560 x 1,440 pixel
resolution will give you more pixels than your computer might be able to
handle. If the screen is your primary concern, it’s also worth noting that the
first-generation 27in iMac (with a Core 2 Duo processor) can now be had for
under £900, £100 less than the cheapest current 21.5in iMac.

Another area where iMacs have always been strong is on the
audio front, something the latest update certainly doesn’t change. Quite how
Apple manages to squeeze so much volume and bass from the iMac’s thin frame and
17watt, down-facing stereo speakers is beyond us, and though clarity is a
little lacking, for general entertainment you don’t really need external alternatives. 

Unsurprisingly, the processor speed in your iMac will depend
on which model you decide to go for. In the 21.5in range, the £999 base model
sports a quad-core Core i5 2.5GHz and AMD Radeon HD 6750M graphics. Our £1,249
review sample ups this to a 2.7GHz Core i5 and Radeon HD 6770M. Though Apple
doesn’t give out the specific CPU model names, we assume it’s the i5-2500S,
which has a Turbo Frequency (the maximum clock speed it can run at when not all
of its cores are in use) of 3.7GHz. The system achieved an Xbench score of 271,
which is not too shabby.


Quite frankly, any Intel Sandy
Bridge quad core CPU
should be perfectly adequate for even demanding users, especially as Mac OS
tends to be a little more efficient than Windows 7.  However, if you do regularly run
CPU-intensive software such as video encoding solutions, there’s the option to upgrade to
a 2.8GHz Core i7 with up to eight virtual cores for an extra £160.

The graphics hardware is essentially mobile chip, as suggested by the ‘M’ behind the 6770 model number. It
features 512MB of memory and is non-upgradeable – if you want better graphics,
you’ll have to plumb for the top-end, £1,650 27in iMac, which gets you a 6970M.
Getting back to the 6770M in our review model, it should be just about adequate
to play many of the games available for Mac at decent detail settings on the screen’s
native 1080p resolution. We tried a game of First Person Shooter CounterStrike:
Source on maximum detail and got a silky 65 frames per second average, though
newer and more demanding titles won’t run as smoothly.


All iMac models come with 4GB of DDR3 RAM as standard, which
should again be plenty for most consumers, though you can upgrade to 8GB or
even a whopping 16GB for a frankly ridiculous £480. If you need lots of memory
on a budget, Macs are not the way to go, as for that upgrade price alone you can
buy an entire working PC with an equal amount of memory!

Permanent storage is more reasonable. On our high-end 21.5in
iMac you get 1TB (1,000GB) as standard, with the option to upgrade to 2TB for
£120 (only twice the ‘regular’ price), a 256GB SSD for a mere £400, or a
combination of both for the bargain price of £600. To be fair though, 1TB
should last most people quite a while.


Things are rounded off by a 720p webcam – or in Apple
parlance, FaceTime HD Camera – to accompany the discreetly integrated

Everyone who has used an iMac in the last few years will be
familiar with the bundled wireless peripherals. First we have the Apple Magic
Mouse, a simply horrid ambidextrous peripheral. Though its touch surface is
kind of cool, it’s not nearly as comfortable as a regular scroll wheel. Worse,
the mouse’s shape provides no support for your hand whatsoever, and it has
sharp edges at the sides which make anything but the most casual ‘claw’ grip
distinctly uncomfortable. 


We would recommend that you go for the Apple Magic Trackpad instead. It makes for an interesting partner to a
less magical but more usable rodent like the Logitech LS1 Laser Mouse, which is available in Mac-friendly white.

The chiclet keyboard, on the other hand, is an absolute joy
to use. You can choose between versions with or without a keypad, and either
way it’s a neat, slim affair. Keys provide excellent feedback with just the right
amount of travel and spring, and layout is flawless. We would happily type on
it all day.


So how does the iMac compare to the competition? If you’re
after Mac OS, it’s the obvious choice – unless you want to take the slightly grey
route of installing Mac OS on a regular PC. Even for Mac power users, the new
iMac is significantly more powerful and better connected than the Mac Pro,
though not as expandable, obviously.

If you don’t mind which OS you go for, the choice becomes
far less straightforward, with rivals like the HP TouchSmart 610 offering compelling alternatives. The 610 might not be as
accomplished in the CPU or GPU departments but it’s still powerful enough for
most users, and offers touch, Blu-ray playback, more storage, more memory, an
integrated TV tuner, a larger screen, better adjustability, a remote control, HDMI
inputs for hooking up consoles, and easier upgrades – all for £150 less. Do
keep in mind though that it doesn’t come close in style, build quality or
slimness, so it’s by no means a clear-cut decision.




Apple has gone the route of “if it ain’t broke don’t fix it”, keeping the beautiful chassis of earlier iMac models in this latest refresh. The addition of Intel’s ‘Sandy Bridge’ internals combines with Thunderbolt connectivity and niceties like an HD webcam to bring these stylish all-in-ones to the cutting edge, finally catching up to high-end Windows equivalents while retaining the killer look that keeps it ahead of the crowd. However, it also retains many of the iMac limitations (including the lack of a Blu-ray drive and easy video inputs), and buying a Windows-based all-in-one will still get you more flexibility while demanding less from your wallet.
