Trendsetting computers that set the bar in 2014 The iMac adds a stunning 5K display for not much more than last year’s high-end model. The design, while not updated, remains the gold standard for all-in-one desktops. Except for the new screen and a different GPU, the components are essentially unchanged from last year’s version. Apple skips 4K and goes directly to what the company calls a 5K display in this expensive, extravagant all-in-one iMac desktop that will appeal to photo and video professionals — or anyone else looking for the best possible screen resolution. A new kickstand makes it easier to set up and use, and the keyboard cover remains a best-in-class example. The Surface Pro 3 is now optimized for a digital pen, which is included. The chassis lacks pen storage, and even with tweaked kickstand and keyboard hinges, the Surface Pro 3 doesn’t fit perfectly on the lap. While this is Microsoft’s best PC to date, it’s more successful as a tablet than a laptop replacement. The high-resolution screen looks fantastic, and the hybrid design still works great as a laptop. The compact Alpha plays a huge library of PC games in a living-room-friendly format, and it works with a standard Xbox 360 controller. The custom user interface is slow and clunky, and the base configuration is underpowered for long-term use. Alpha makes good on many parts of its promise to meld the gaming PC and living-room game console, but there are still too many rough edges to make this a true console killer.
