You get a new computer and it runs great. However, after a while, things start to get more and more sluggish. This is true for all operating systems, including those running the all new and shiny Windows 7.

That is because, other than user errors (such as misuse, viruses, spyware, accidental file deletion, harmful changes to the Registry and system settings, and so on), the OS doesn't take good care of itself. It collects and store junks from the Internet. It doesn't completely remove remnants of unwanted applications. Its Registry keeps getting more and more bloated with residual settings, and so on and so forth. All of these result in system clutter that over time slows down the machine.

With a burst of renewed interest in 3D technology, Acer seems to be slightly ahead of the curve with its Aspire 5738DG laptop, featuring a special combination of hardware and software to add 3D to games, photos, and videos. Thanks to projects such as James Cameron's Avatar, upcoming 3D TV monitors, and Nvidia's 3D Vision project, consumers are hearing more about 3D than any time since the 1950s.

The $779 Acer Aspire 5738DG takes a different approach than the 3D Vision product from Nvidia. While the Nvidia rig requires a desktop PC with a high-end video card, a dual-link DVI connection to a compatible 120Hz LCD monitor, a USB-connected emitter box, and a set of active, battery-powered glasses, Acer's laptop is mostly software-driven, using a special screen coating and standard polarized-lens glasses to produce the 3D effect.

Like the Nvidia 3D vision setup (previously reviewed here), movies and photos need to be rendered in a 3D format to be used, but virtually any video game will work, as long as it makes use of actual 3D data to generate its characters, settings, and in-game objects.
