The Spacetop AR laptop made a splash when it debuted a few years ago with an intriguing pitch: What if you could have a notebook that works entirely through augmented reality glasses, without a built-in screen of its own? Unfortunately, we found the Spacetop experience to be underwhelming, and the hardware seemed like a tough sell for $1,900. Last Fall, Spacetop's creator Sightful told CNET that it was abandoning the screen-less laptop altogether and instead focusing on building AR software for Windows PCs. Now, we have a clearer sense of what Sightful is up to. Today, Sightful is officially launching Spacetop for Intel-powered Windows AI PCs, following a short trial launch from January. For $899 you get a pair of XREAL's Air Ultra 2 glasses and a year of Spacetop's software. Afterwards, you'll have to pay $200 annually for a subscription. The software works just like the original Spacetop concept it gives you a large 100-inch AR interface for doing all of your productivity work except now you're not stuck with the company's middling keyboard and other hardware. Spacetop might be compelling to AR fanatics who already own Intel AI PCs like the Surface Laptop Pro for Business, or a Dell XPS machine with the Core Ultra 7 chip. But if you don't have one of those computers, you'll have to add it to Spacetop's already high cost. And don't forget about prescription lenses: Those will run you $50 for single-vision and $150 for progressive. Spacetop doesn't support Intel chips without NPUs, as its AR interface requires constant AI processing. It doesn't work AMD or Qualcomm's AI CPUs, either. The company partnered with Intel to optimize Spacetop for its platform, which included help with understanding Intel's NPU architecture as well as tweaking its chips to help the AR software run better. In a conversation with Engadget, Sightful CEO Tamir Berliner noted that the company might pay more attention to other chip platforms if it gets similar attention. As for Mac support, Berliner said in a statement to Engadget: "Yes, we plan to create a version of Spacetop for Mac the timing is still TBD based on a lot of different factors regarding laptops, silicon, compute power, glasses, and more. We will be excited to share more news when we are able. Given its price and the strict PC requirements for using it, Spacetop clearly isn't meant for a wide audience. But there are potential benefits for early adopters. Its large AR screen could make it easier to multitask without large monitors, and it's also easier to focus on your apps since Spacetop vastly simplifies the Windows 11 interface. There are some obvious privacy benefits, too, since no one else can see what you're looking at in AR. The big downside, though, is that you'll have to get used to wearing Xreal's large Air 2 Ultra glasses. When we demoed it at CES, we found it to be an improvement over previous Xreal frames, thanks to their sharp 1080p micro-OLED displays and wider field of view. The Air 2 Ultra are also notable for having 6DoF tracking, which allows you to move around AR objects. While sleeker than the Vision Pro, the glasses are still pretty clunky, and you'll also have to snap in additional prescription frames if necessary. I'll need to see this latest iteration of Spacetop in action before making any final judgments, but it's clearly a more viable concept as an app that can work on a variety of laptops. Nobody wants to buy bespoke hardware like the old Spacetop laptop, no matter how good of a party trick it may be.This article originally appeared on Engadget at https://www.engadget.com/ar-vr/spacetop-ar-is-now-an-expensive-windows-app-instead-of-a-useless-screenless-laptop-140030911.html?src=rss

Perplexity has rolled out an update for its iOS app, giving iPhone users access to its AI voice assistant that was initially released for Android users earlier this year. Its voice assistant can perform tasks for the user by browsing the web or accessing other apps for them. If they ask the assistant to find them a table for a specific restaurant, for instance, Perplexity can launch the OpenTable app with the number of people, the date and the time already filled out. The user still has to perform the final action and book a reservation, but it's already laid out for them all they have to do is click the button. Users can also ask the assistant to draft emails for them for specific contacts, which they'll have to send themselves, and create reminders for them on the calendar. They can ask it to recommend them spots they could visit, such as restaurants serving food they want to eat, and Perplexity will mark locations on the map. Of course, they can ask the assistant to do web searches for them, such as finding specific videos that Perplexity can open on the YouTube app. As The Verge notes, Perplexity's voice assistant works on older iPhones, unlike Apple Intelligence that only works on the company's more recent models. The iOS assistant also doesn't have the capability to look at the world for the user and tell them what they're seeing yet, though the feature is already available on Android and could make its way to iPhones in the future.

In case you're wondering how Moore's Law is doing, Taiwan Semiconductor Manufacturing Corp. (TSMC) just unveiled its latest 1.4-nanometer (nm) A14 process that will enter production in 2028. The technology promises a 15 percent performance boost, plus a 30 percent reduction in power draw compared to 2nm processors set to go into production later in 2025, TSMC said. The 1.4nm tech is likely to be used in processors for Apple, Intel and AMD. The performance gains are thanks to a 20 percent logic density improvement over 2nm tech. The company's 2nm process saw similar improvements over the 3nm chips, so the 1.4nm chips could be up to 30 percent faster and 60 percent more efficient than current chips. Apple's chips today are based on TSMC's 3nm process, and the upcoming iPhone 17, including a rumored ultra-slim version, will reportedly use that as well with the third-generation N3P node. So, Apple won't likely switch to TSMC's 2nm tech for another two years, as MacRumors pointed out. That in turn means Apple won't likely employee 1.4nm tech in mobile and desktop devices for three or more generations and it could be that long before we see it in AMD and other processors as well. However, TSMC usually has multiple generations of a given node (with small improvements in each), and Apple has been adept at boosting performance of its Silicon design before switching to smaller processes.
