  • A great in one desktop PC for those with less funds, but have needs for rich features to produce computing and internet based tasks, easy to accomplish. May well have the bells and whistles like those available from the Apple iMac MD093LL/A 21.5-Inch Desktop, however it has all the key features you'll want a fantastic computing experience.


  • Finally, Lenovo IdeaCentre C345 has a lot of things to offer to us all. We will surely not regret once we have decided to purchase this device. Keep your eyes open as you experience real satisfaction with this All-in-One Desktop.


  • Apple sticks to the fundamentals with the new iMac, relying on design, strong features, and overall polish to maintain its leadership among high-end all-in-ones.


  • Slimmer and faster, the Apple iMac 21.5-inch (Late 2012) is the desktop PC to buy if you're looking to avoid the whole touch-screen conundrum. The new iMac upgrades components, looks great, and has the power to do real work in a business or at home.


  • It goes without saying that there are numerous Windows PCs that can provide comparable performance at a lower price. However, few of them - nay, none - can match the build quality or the luxurious 27in screen of the iMac. That screen is ideal for graphics and video work and will appeal to home users and professionals alike. Yes, it's expensive, and it lacks features such as a solid-state drive that perhaps ought to be standard.


  • It's the best of the small handful of current tablet/all-in-one hybrids, with a subtle, sophisticated design and good battery life, but this new genre is still in its early days.


  • The Dell XPS 18 fulfills a niche somewhere between a large screen ultrabook and a dedicated all-in-one desktop PC. It mostly works, though the market for such a product is still in its beginning stages.

  • Vizio's top-of-the-line 27-inch touch all-in-one gets a modest update but stays traditional compared with detachable, convertible alternatives.


  • With its great feature set and lots of performance, the Vizio 27-inch All-in-One Touch PC (CA27T-B1) is a system that can deliver on the promises made by its futuristic design.


  • Vizio's latest all-in-one looks good and performs well, but Vizio needs to up its peripherals game.


  • The Vizio 24-inch Touch All-in-One (CA24T-B0) PC looks great, and doubles as a pretty good HDTV.


  • Price is the biggest bugaboo with the CA24T. As with most all-in-ones, you pay a lot extra for the style and the space-saving design. But unlike much of the competition, the CA24T actually delivers on both counts. An AIO should have more than looks, though. For this price, Vizio could provide a better keyboard, plus mouse and SSD options. (It should also have a discrete GPU option for its Intel-based model.)
