Have you ever looked to a future without keyboards and mice? Today we review two PCs that not only integrate everything, including their screens, into one enclosure, but also include touchscreens. Best of all, both models sell for less than $700.

Power Consumption

It's not a surprise that both all-in-one PCs consume more than 50 W (more power than a monitor alone), but it's important to keep in mind that none of our LCD figures include the power consumption of a system. As a reference point, Samsung's PX2370 consumes about 57.2 W when we include the power consumption of our Sandy Bridge system (Core i5-2500K/Asus P8P67 Deluxe).

It's disappointing to see that the ZX4931 uses more than 2 W when it’s in standby mode. An energy-efficient system should consume less than 1 W when it’s off, and not more than 1.5 W in a standby state.
