The Lenovo C315 is perhaps the most affordable all-in-one PC featuring a touch screen with a non-Atom processor. (A slightly lower model than the review sample with a 320GB hard drive and 2GB of RAM can be found at the Lenovo website on sale for $749.) It has other merits as well, being well built, attractive, and possessing a crisp, clear 20" high definition display that has less glare than most LCDs. With discrete graphics, the ATSC tuner and IR remote control, it makes a fairly decent home theater PC, though a better set of speakers would be a must. Oddly enough, the IdeaCentre, which is supposed to be a more entertainment-oriented all-in-one, lacks both a TV tuner and remote control.

The C315's main draw, the touch screen, really doesn't belong on a desktop PC in our opinion. Fatigue sets in quickly when you hold your hand two feet in front of you for lengthy stretches and it is rather difficult using your finger to make precise contact and movement on a high resolution screen. Though the experience would undoubtedly improve with practice, we don't see it ever being easier and/or faster than a mouse and keyboard for anything except drawing. Perhaps it may become more practical in the future, but currently the technology seems infinitely more useful on mobile devices like tablets and phones that are too small for a keyboard and mouse.

The machine has a few major failings with noise being at the top of our list — it is easily the loudest all-in-one we've tested and unbearable by SPCR standards. The hard drive seems to be the main culprit, producing a hum at 120 Hz that almost drowns out any other noise being generated elsewhere in the machine. A move to a 5400 rpm hard drive would help alleviate this problem, and the performance downgrade would likely go unnoticed given the system's relatively slow processor. Some form of mechanical decoupling is probably needed to really bring the HDD noise down. The Athlon II X2 250u, while certainly faster than any Atom, is significantly slower than any desktop Athlon X2 or modern Core 2 Duo except for CULV (consumer ultra-low voltage) models. The C315 also doesn't appear to lower the operating voltage of the CPU when idle, resulting in rather high idle power consumption.

Our thanks to Lenovo for C315 all-in-one PC sample.
