Spacetop G1 is a canceled augmented reality laptop developed by the Israeli company Sightful. Instead of a built-in screen, it used a pair of Xreal AR glasses, a head-mounted display wired to the keyboard base, to show a virtual workspace that Sightful described as equivalent to a 100-inch screen.[1][2] It was the successor to the Early Access version of Spacetop, which Sightful had sold since 2023.[3]
Sightful announced the Spacetop G1 on 30 May 2024 at a price of US$1,900, took US$100 refundable reservations, and planned to ship it in the United States in October 2024.[2][4] The device never shipped. On 8 October 2024 Sightful canceled it, offered refunds of the deposits, and said it would no longer ship hardware and would instead develop Spacetop software for Windows laptops.[5][6]
Background
Sightful was founded in 2020 by Tamir Berliner (chief executive) and Tomer Kahan (chief operating officer), both former Magic Leap executives, and is headquartered in Tel Aviv.[2] The company opened an invite-only Early Access program for the first Spacetop in May 2023. On 9 January 2024 it made the Early Access Spacetop available to anyone for US$2,150.[7] Tom's Guide first tried the Early Access version at CES 2024.[1] According to UploadVR, Early Access units had shipped to hundreds of buyers in 2023, and the G1 was an upgraded model intended for a wider consumer release.[3]
Compared with the Early Access model, Liliputing reported that the G1 had a processor Sightful described as 70% faster, longer battery life, twice the RAM (16 GB instead of 8 GB), faster wireless networking, and a color OLED status display in place of a 1.54-inch black-and-white ePaper screen. The webcam was also moved higher on the device.[8][2][1]
Announcement
Sightful unveiled the Spacetop G1 on 30 May 2024. It listed the price as US$1,900 with shipping in October 2024, United States only, and prescription lenses included at no extra cost. A US$100 deposit reserved a unit and could be canceled at any time before shipping.[4][2] UploadVR reported that, for one week, reservations came with a US$200 discount.[3]
In an interview with Inverse, Berliner described the approach this way: "Instead of getting a platform that showcases the future, let's build a use case that people can use."[9]
Design and hardware
Base unit
The Spacetop G1 looks like a laptop with the screen removed above the hinge. A folding fabric cover with a hard shell holds the 5-megapixel webcam and a storage compartment for the glasses. Because the glasses are hardwired to the base, they cannot be detached for storage; closing the cover leaves a visible bulge in the middle of the device.[1]
According to Sightful's specifications, the base measures 30.0 x 23.1 cm, is 1.3 cm high at its thinnest and 6.2 cm at its thickest point, and weighs 1.4 kg. It has a 79-key full-size US English keyboard, a 135 x 85.5 mm multi-touch trackpad, and a full-color OLED mini-display of 262 x 928 pixels above the keyboard.[4] Tom's Guide noted a key marked with a star icon that Sightful called an "AI" key; the company did not say what it would do.[1]
Processor, memory and battery
The G1 uses the Qualcomm Snapdragon QCS8550 platform with a Kryo CPU, an Adreno 740 GPU and a dual eNPU rated at 48 INT8 TOPS. It has 16 GB of LPDDR5 memory and 128 GB of UFS 3.1 storage, of which 102 GB is available to the user.[4] UploadVR referred to the chip as a Snapdragon 8 Gen 2 and reported that the device uses active cooling.[3]
Sightful specified a 60 Wh battery rated for up to 8 hours, charging from 0 to 85% in less than two hours with a dual-port USB-C adapter of up to 63 W.[4] Road to VR and PCWorld reported the battery life as up to seven hours.[2][10]
Glasses
Sightful's specification sheet lists two OLED display panels with 1920 x 1080 pixels per eye, a 90 Hz refresh rate, a 50-degree diagonal field of view and 44 pixels per degree; the glasses weigh 85 g.[4] Road to VR, PCWorld and Tom's Guide gave the angular resolution as 42 pixels per degree.[2][10][1] Custom prescription lenses for corrections from -8.00D to +6.00D were to ship with each unit.[4] Tom's Guide reported a button on the side of the glasses for dimming them to suit ambient light.[1]
Sightful did not name the glasses model on its specification page.[4] Road to VR, UploadVR and Inverse identified them as the Xreal Air 2 Ultra, and UploadVR described them as using transparent birdbath optics with 6DoF tracking.[2][3][9] PCWorld and Liliputing instead described the glasses as a modified Xreal Air 2 Pro.[10][8] PCWorld reported that the refresh rate was raised from 72 Hz on the earlier Spacetop and the field of view reduced from 53 degrees.[10]
The glasses have two open-ear speakers, and the base has 6 W stereo speakers.[4]
Connectivity
The G1 supports Wi-Fi 7, Bluetooth 5.3, and 5G/LTE (Sub-6) with an eSIM and a nano-SIM slot. It has two USB-C ports rated at up to 10 Gb/s.[4] According to UploadVR, the ports handle charging and a 1080p DisplayPort mirror output.[3] Tom's Guide noted that one of the two ports is needed for charging and that the device has no headphone jack.[1]

Software
The G1 ran SpaceOS, Sightful's own operating system. Sightful said SpaceOS was "built for the modern Web".[11] Road to VR described it as Android-based and focused on web apps, without initial access to the Google Play Store, and Sightful's developers told Gizmodo that it was based on a heavily modified version of the Android Open Source Project that allowed multiple windows.[2][12] Liliputing reported that it was built on ChromiumOS.[8]
Tom's Guide reported that at launch the G1 would run web applications like a Chromebook, including Google's apps, Microsoft 365, Slack and Zoom, and that Sightful said support for installing Android apps might be added later. Unlike a pair of AR glasses connected to an ordinary laptop, which shows the desktop fixed in front of the wearer, SpaceOS lets users place windows around themselves in space, resize them, and keep the layout for later sessions using the sensors in the glasses.[1] The Early Access software had earlier gained a live-streaming feature for sharing a first-person view of the workspace and a motion stabilization mode for use in cars, trains and planes.[7]
Cancellation
On 8 October 2024 Sightful canceled the Spacetop G1, emailed customers with reservations to offer refunds of their US$100 deposits, and said it would no longer ship hardware.[6][5] Berliner and Kahan said the decision followed the arrival of laptops with neural processing units (NPUs), which could run 6DoF tracking without reducing performance or battery life, and that offering Spacetop on existing Windows laptops gave the company a much larger potential market.[5] Road to VR reported that the new software would first support Xreal glasses over USB-C, with Mac support planned after launch.[6]
Sightful released Spacetop for Windows in April 2025 as a US$900 bundle with Xreal Air 2 Ultra glasses and one year of software, requiring an Intel Core Ultra laptop at launch.[13]
Reception
Because the G1 was canceled before shipping, press impressions come from short pre-release demonstrations. In his hands-on for Tom's Guide, Alex Wawro wrote that he was "tentatively excited". He found the virtual display easy to see and videos sharp regardless of head movement, and SpaceOS responsive during multitasking. He also found the case ungainly to carry with the glasses hardwired to the base, and the webcam angle unflattering.[1]
Kyle Barr of Gizmodo said he "had no problem reading text on a page" but that the 50-degree field of view meant turning the head more to see everything. He called the glass trackpad a standout and found the keyboard somewhat hollow, with minimal key travel. The software was slightly buggy during his demo, and few apps worked natively on the device, so services such as Instagram and YouTube had to be used in a browser.[12] Writing for Inverse, Ian Carlos Campbell raised the limited field of view and the reliance on web apps as open questions about whether the device justified its price.[9]
