We reviewed Acer's 3D laptop not so long ago. We found it fun, but reeking of gen 1 quirks. Now Laptop Mag has played with a new 3D laptop by Asus and found it to be pretty fantastic.
The Asus G51J 3D is the first laptop to feature NVIDIA's new 3D vision technology, and it takes advantage of a high performance, 15.6-inch 120Hz LCD that, when coupled with shutter glasses (yup, you still need glasses) garnered these praises from Laptop:
...unlike the TriDef technology that powers Acer's 3D laptop, titles optimized for 3D vision give you a great sense of depth without negatively affecting gameplay. On first person shooters, for example, we found it difficult to aim when using the Acer 5738DG. On the Asus G51J 3D, you don't make any compromises in terms of control or accuracy.
For the 3D tech, you'll take a resolution hit (there's no 3D 1080P display option) and pay a $200 premium, making the full gaming $1,700.
Keep in mind that Acer's system, while utilizing only rudimentary polarized glasses 3D, costs under $800. [Laptop Mag]
