Almost exactly a year after Nreal unveiled its Air augmented reality glasses, the company is bringing the device to the US. Nreal Air, which the company is pitching as a device for streaming shows and playing games on, is available from Amazon starting today for $379. As with Nreal's $599 Light glasses, the Air will need to be tethered to a phone or other device. That could be a little easier if you snap up the new $59 Nreal Adaptor, an HDMI-to-Lightning dongle for iPhone.

In line with that peripheral, Nreal has upgraded the Air's iOS and Mac compatibility. At the outset, the Air will offer screen mirroring from iOS — Nreal's Nebula operating system doesn't run on iPhones yet. Still, you'll be able to watch streaming video services on a virtual 130-inch display.

That said, a version of Nebula will be available for MacBook Pro and MacBook Air laptops, Nreal said. When you plug the Air into a Mac, a user interface called AR Desktop will open up. You'll be able to view multiple virtual displays at the same time, which could make the Air useful if you need more screen real estate while travelling.

The company has also redesigned Nebula. In particular, the AR Space experience, which Nreal users see when they open Nebula, now has a borderless curved wall design and animated menu icons. Users will receive recommendations for content through a new widget, which offers the option of previewing apps without having to open them. The Spatial Browser offers a horizontal mode (for multi-window web browsing) and a vertical mode for sites that demand a lot of scrolling.

In addition, Nreal is adding more casual games and a pair of new apps. The first of those is called Teleport, which will allow you to explore 3D models of real-world objects that have been scanned with phones. You'll be able to leave photos for other users, as well as voice and text messages. Teleport will be available later this year. Meanwhile, Mirror Mode enables users to play PC and console games on a 200-inch virtual screen. Cloud gaming services such as Xbox Cloud Gaming are supported too.
