It's everywhere now: 3D.

It's everywhere now: 3D.

The 3D TVs have been around for about a year. Since then, 3D has also crept into certain still and video cameras, Blu-ray players and gaming systems. This past week Nintendo unveiled its 3DS handheld gaming system, and this summer will bring several new cell phones with 3D capabilities.

So, 3D or not 3D? That is the question.

The Nintendo 3DS (available at Best Buy and Target for $250) went on sale last Sunday. Supposedly, it was Amazon's most pre-ordered product ever.

The gadget has a clamshell design. The bottom panel has a 3-inch LCD touchscreen, while the signature 3.5-inch 3D screen is found on the underside of the lid. This screen uses a "parallax barrier" display, which means you can see 3D images without wearing glasses.

When it's held 12 inches from your face, 3D images come to life. The 3DS has a 3D depth slider to intensify the image, plus built-in motion and gyro sensors.

The 3DS can take 3D photos. By summer, it'll even be able to stream 3D movies from Netflix.

Sprint recently announced that this summer they'll be selling a 3D smartphone - the HTC Evo 3D (price TBA) - that will operate on Sprint's 4G WiMAX network. Users will view 3D hologram-like images on its 4.3-inch display without wearing glasses.

The phone will be able to send content to a 3D-capable TV through its HDMI port. It'll have a 1.2 GHz dual-core Snapdragon processor (reportedly making it the fastest smartphone on the market) running on an Android operating system. The gadget will sport two 5-megapixel cameras for recording conventional and 3D photos/videos.

Meanwhile, AT&T announced a summer debut for their LG Thrill 4G (price TBA), a cell phone that also lets users shoot and view 3D images. The gadget will have a 4.3-inch stereoscopic 3D display and will operate on AT&T's 4G speed network. It'll also have a dual-core 1GHz processor and a 5-megapixel dual camera.

The phone will feature 16GB of memory and will record 3D video at 720p and 2D video at 1080p. Even better, it will have direct connectivity to YouTube 3D.
