Reviews for the Acer Aspire M5-581TG-6666
Source: Techspot

When I first fired up the TimelineU, I had a hard time determining whether I should review the machine objectively as a standalone product or if I should impart my preconceived notions about ultrabooks. In the interest of fairness, I'll try to cover both starting with the latter: As an ultrabook, the M5 falls short.

The Acer Timeline Ultra M5 is yet another Ultrabook on the scene. This one offers an attractive design, great audio, an optical drive and discrete graphics. It does lack in screen resolution and overall performance, which holds this computer back from the rest of the pack.

The Timeline Ultra M5 runs on a newer but weaker processor than the M3 used, and Acer pulled the older model's speedy 256GB SSD in favor of a 500GB HDD with a 20GB SSD boot drive. The result is slower overall performance, which is reflected in the 50-point difference in the systems' WB7 scores.

With most 15.6-inch notebooks, you're forced to lug around a bulky, heavy device, sacrificing thickness for power. The $829 Acer Aspire TimelineU M5-581TG-6666 is a happy compromise, stuffing a slim 0.81-inch chassis with an Ivy Bridge CPU, discrete Nvidia graphics, and more than 7 hours of battery life, which will delight mobile gamers and multimedia consumers everywhere.
