If you consider the ultrabook definition by Intel’s vision, these two machines don’t have the look of standard ultrabooks, although technically fulfills all the criteria. What these two machines have in common? Both are two great options for consumers that are more focused on the multimedia section.
The refresh version of Vaio Z fits more properly in the ultra portable machines category with a new design using a solid aluminium material mixed with carbon fiber, while the Aspire Timeline Ultra M3 is made of plastic with thin metal components, making the machine a solid yet good looking one.
In terms of precise dimensions, Sony’s refresh Vaio Z is lighter and thinner than Acer’s new Aspire, although both have a classy and elegant form factor. Still, the Vaio Z has a smaller 13.1-inch display than Acer Aspire M3 that comes with a larger and standard size screen for classic notebooks: 15.6-inch.
Underneath that polycarbonate construction used, the Aspire Timeline Ultra M3 prouds itself with Nvidia’s new GeForce GT 640M WITH new Kepler architecture that can play graphically intensive games. Sadly, the screen resolution is low with bad viewing angles, in comparison with Sony Vaio Z.
The battery life doesn’t really last eight hours, but you can get around five hours of daily tasks, but it all depends on what exactly each users does with the machine. As a traditional ultrabooks, the Aspire Ultra M3 isn’t quite a success, but for a 15-inch gaming laptop is quite a good investment, considering also the price point.
A light and thin gaming laptop is hard to reach, but we assume the design shouldn’t be a must have factor when choosing such a machine. But you can also choose theVaio Z which is slimmer, lighter, has a better screen resolution and comes with an external GPU (1GB) plus a  metal and stable  Power Media Dock. Equipped with the newest and greatest components around, the new Vaio Z is a really powerful machine yet expensive.
