The already impressive 27-inch 5K iMac gets some welcome spec upgrades for 2017, but rival Windows machines have closed the gap.
While its sealed-case limitations will turn off power users, Apple's least expensive Mac delivers a solid OS X experience in a compact box with similar performance to the entry-level MacBook Air and iMac models.
The iMac is still the best all-in-one desktop on the market. We love the physical design of the system, and the new components on the inside make it very quick. Our only real gripe is the fact it's difficult to upgrade after purchasing, and upgrading at the point of purchase will cost you an arm and a leg
Whichever way you look at it, the HP Pavilion Elite m9000 series (m9065.uk-a) is a good PC. Better value can be had elsewhere, but its quad-core CPU, ample memory and thoughtful design helps it stand out from the crowd
The Packard Bell oneTwo may not offer the best touchscreen experience, but its built-in Freeview TV tuner and ability to link games consoles via the HDMI-in port makes it a good choice for a student flat or as a second family computer.
The all-in-one Acer Aspire Z5771 desktop PC offers good performance for an affordable price, making it a wise choice for family computing. The absence of a Blu-ray drive and the lacklustre screen means it won't appeal to movie lovers.
The Sony Vaio XL302 is a hugely impressive Media Center PC. It packs everything you could want into its large frame, including dual TV tuners and a Blu-ray drive. But for £700 less you can get the very similar, Blu-ray-less Sony Vaio VGX-XL301
The Lenovo IdeaCentre A720 offers a 27-inch Full HD screen along with a Blu-ray player, powerful internal components and sleek, stylish looks making it a good option for someone looking for a TV-cum-computer for the living room.
We really like all-in-one PCs, but the IQ810 is rather pointless. Touchscreen displays don't really work on screens of this size because they make your arm tired from waving all over the place. If you want an all-in-one PC there are better designed options available
The iMac Pro is everything we thought it would be -- good and bad.
The Packard Bell oneTwo L I7526 is a decent option for those who fancy a touchscreen PC with an integrated TV tuner, but don't want to spend a fortune. It offers good performance, inoffensive looks, passable sound quality and a big, 23-inch screen.
The Acer Aspire 5600U packs a vivid high-definition touch-enabled screen into a slim and attractive body, making it a good choice for family computing in the living room. It's sadly let down by only average performance that doesn't help justify the relatively high asking price.
The tiny Dell Inspiron Zino HD 410 may not be hugely exciting, but it will do a decent job of handling your media, without taking up much space.
Lenovo's latest all-in-one desktop offers a full-HD display at a budget price and with an admirably small footprint.
It does exactly what it says on the tastefully white-coloured tin. The 5100 is ready to be dropped into the heart of any house as a general purpose email, Web and office task platform
Acer's Predator rollouts include a funky new flagship gaming desktop, 3D sound and a mouse that may save you some ammo.
The Dimension 5150c is one of the first PCs to use the Intel Viiv specification, and it makes a good first impression. Its BTX chassis almost achieves the Holy Grail of silent operation. Useless at running games, its Pentium D processor gives it strong performance elsewhere, and it is surprisingly inexpensive. Some users will be disappointed at the lack of a TV tuner, but if recording television isn't a priority then the 5150c is a winner in almost every respect
The Asus Tytan CG8890 packs in some of the most powerful components a non-military professional has access to. It can tackle the glossiest games with the sort of cool ease most desktops can only dream of but it does demand £4,000 in return. If you custom built a similar rig elsewhere, you could save yourself a bundle.
