The already impressive 27-inch 5K iMac gets some welcome spec upgrades for 2017, but rival Windows machines have closed the gap.
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 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 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 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.
The IQ500 is the best all-in-one PC we've seen to date. It's the epitome of style, has very useful features and is versatile. The jury's still out as to whether a touchscreen is absolutely necessary, but those who want a compact, fun PC that's a little out of the ordinary should definitely consider it
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.
We find it difficult to fault the Elite Quad 6600 FX. It has a fast quad-core processor, ample memory and a graphics card that while not particularly fast, doesn't shy away from games. If you have a spare £700 and want a solid all-round PC, you really should consider it
The HP Omen X builds a powerful gaming desktop with smart ergonomics into a bold but expensive statement piece.
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
Apple's refreshed iMac isn't very ambitious, but it's still the most attractive, elegant and eminently usable all-in-one computer out there. It's extremely expensive compared to its Windows rivals, but the iMac is great fun to use.
The SmartTV S320 is a very good Media Center PC. It has plenty of storage, good performance and it will happily show high-definition content. Where it falls down slightly, however, is its inability to work as a standalone television and its questionable image quality
It's difficult to find fault with the VGX-XL202. It's powerful, looks good and is packed to the brim with high-performing, but quiet-running components. It's the ideal Media Center PC for anyone who wants to get an early ride on the Blu-ray bandwagon
The Aspire E300 is a massive departure from the Alienware and Dell offerings that dominate the gaming arena. It's nowhere near as expensive and its contemporary styling should appeal to a broader audience. It can't compete with high-end gaming rigs, but Acer has used relatively high-performance components. It'll whiz through most everyday applications, so it's ideal if you're after a cheap desktop that covers all bases
On the whole, the Medion Akoya P4011 D is an attractive and capable all-in-one PC. It's slightly too slow for our liking, though, and we're not convinced that waving your arms about like Tom Cruise in Minority Report represents the future of computing. But, if you're looking for a next-generation desktop PC that doubles as a telly, it could be right up your street
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
A winning design and unusually good sound system highlight HP's first-rate reimagining of the HP Envy Curved AIO 34 for 2017.
