All-in-one PC reviews: Features explained
The beauty of the all-in-one PC is that it combines many of the advantages of the desktop PC and the laptop PC in one convenient, and usually stylish, package.
All in one pcs vs laptops vs desktop pcs
Like a laptop, the all-in-one is relatively compact and easy to set up; just plug in the keyboard, mouse and power supply, and you’re up and running. The simple, one-box design is also a lot more attractive than a bulky, noisy PC unit and a separate monitor, with chunky cables running between the two.
As with a desktop, however, you get a full-sized screen and mouse and keyboard, which make the all-in-one more comfortable to use over long periods, and better equipped for watching videos or doing creative work. An all-in-one will usually have better sound than a laptop, and a greater range of connections for hooking up cameras, printers, external hard drives and other devices.
Of course, the all-in-one also has some negative qualities. Like the laptop, it’s not usually upgradable beyond adding more Ram, while a tendency to use laptop components means that an all-in-one won’t usually have the performance of a similarly priced desktop PC. On the other side, all-in-ones still use more power than a laptop, and can be folded away when the day’s work is done. Those stylish, slimline designs also come at a price. An all-in-one PC invariably costs more than the equivalent desktop PC and monitor, bought separately.
With that said, the combination of style, comfort and convenience still makes an all-in-one a great home PC. If you’re in the market for one, there are a few things you need to think about.
With a desktop PC you can replace the monitor, but with an all-in-one, you’re stuck with it. Size matters, but the exact size depends on what you plan to do with it. If you just want a basic PC to use the internet, send email and write letters, then a 19-inch or 20-inch model will be perfectly adequate. If you want something to watch films, adjust photos and play games on, then a larger screen makes more sense, as does a 1,920 x 1,080 resolution. It’s the same resolution as a Full HD TV set, and you’ll appreciate the extra pixels should you start watching or editing HD content or photos.
Touchscreen all in one desktop pcs
Windows 7 has made big strides towards bringing touch controls from the smartphone to the desktop, and a number of all-in-one PCs have embraced this. To be honest, it’s not that compelling a feature right now. While you can use Windows through touch alone, the interface and many applications aren’t really designed for it.
Children and less-experienced users sometimes take to a touchscreen faster than a mouse, and there are some nice note-making and calendar apps around, but generally, if the choice is between a touchscreen and a faster processor or bigger screen, opt for the latter.
Intel and AMD both now have a bewildering range of processors available. Intel’s line starts with the Celeron, moves up through the Pentium dual core and into the Core 2 line, and from there goes to the newer Core i3, i5 and i7 lines, while AMD has its own Athlon and Phenom lines. Even within those categories, you’ll find dual core processors, dual core processors with HyperThreading (HT) which behave like four core processors as well as true quad-core and six-core processors.
More cores are good if you’re planning to get involved in creative work with video, 3D or graphics, but a dual core processor has enough power for most programs. Beyond technical differences, cheaper processors usually have smaller amounts of cache memory – Ram built into the CPU and used to store key bits of data that the processor needs to work on.

AMD Phenom III
- Features: Quad core and six core
- Applications: All programs
Windows 7 and Mac OSX are both memory intensive, and it’s worth having 4GB (or more) to keep all your applications running smoothly. Note that many all-in-ones now ship with all their memory slots already occupied, so to upgrade later, you may need to jettison some existing Ram.
The hard disk drive provides primary storage space for your operating system, your applications, your documents, photos, music files and video files. These files get larger as applications grow more sophisticated or digital cameras develop higher resolutions, so the bigger the hard disk the better.
Some hard disks are noticeably faster than others, with much depending on the spin speed, or the rate at which the magnetic platters inside the drive rotate. As a rule of thumb, a 7200rpm hard disk will load or transfer files at a faster rate than a 5,00RPM drive, meaning less waiting for you while a program loads or a batch of photos copies over.
Note, however, that you can add a USB hard disk to your PC later to take some of the load from your primary HDD.
Most, if not all all-in-ones come supplied pre-installed with Windows 7 or Mac OSX 6 Snow Leopard. Both are efficient, attractive and easy to use, and which you opt for is pretty much a matter of personal taste.
There’s good reason for choosing a Mac if you already have an iPhone and iPad, and ditto if you have a notebook or netbook and a Windows 7 Mobile phone. You can, however, install Windows on an iMac and switch between the two systems, should you wish.
With a TV tuner, an All-in-One PC transforms from a simple computer into a multimedia powerhouse that can be used to watch and record Freeview TV, using the Media Center software built into the Home Premium and Ultimate editions of Windows 7. Many of us might never use this feature, but it’s ideal if you want a PC to double as a second TV set, or if you’re buying a computer for your children to take to university.
DVD rewriters are now standard across most desktop computers, and give you a great way to back up photos, share home videos and archive documents. A few all-in-ones now ship with Blu-ray drives installed, enabling you to watch HD movies on an HD screen without investing in a Blu-ray player for your TV.
Another area with a bewildering range of options. Some all-in-ones use integrated graphics, provided by Intel or AMD as part of the motherboard chipset, and in nearly all cases offer respectable performance in 2D applications, but terrible performance in 3D. If you want to play games or enjoy HD video, then look for something with a discrete graphics processor from nVIDIA or AMD, and – as a rule of thumb – the higher the number the better.
Wired networks are rare within the home, and it’s only once you’re streaming video or copying huge documents across the network that the difference between the basic 100BaseT Ethernet standard and the faster Gigabit Ethernet standard make themselves felt.
What might be more crucial is the difference between the old 802.11g wi-fi standard and the newer 802.11n. 802.11n doesn’t just give you faster connections; it also improves the reliability of the connection through thick walls and over long distances, making it particularly important if you plan to use WiFi in different rooms of your house. Bear in mind, however, that you’ll need an 802.11n compliant router to gain any advantage from having 802.11n networking in your PC.
