There’s never been a better time to buy the EcoFlow Delta Pro Ultra. Adrian Kingsley-Hughes/ZDNETI test portable power stations for a living and hear from a lot of readers who’d love to get their hands on one, either for use at home as a backup power source or in a truck or RV for camping, but the cost puts them out of reach. I understand — they’re not cheap. Some are hundreds of dollars, others are thousands, so being able to grab a good deal is a great idea. And premium manufacturer EcoFlow is having a winter sale, so there’s never been a better time to prep for that next storm, power outage, or camping trip. But hurry, because these deals run until February 9th, after which they’re gone! Also: The best portable power stations you can buy Top EcoFlow deals More

Opera I’ve been using Opera for a long time, and I’ve watched it evolve from a fairly basic browser to a full-on efficiency machine. A big part of Opera’s appeal is how it manages tabs. Opera was the first to bring out Workspaces, where you can group tabs together in a way that prevents overcrowding […] More

David Gewirtz/ZDNETAs a tech professional, there are many things I know because I know things. But there are also things I learn about because it’s my job to fix the tech problems around the house. In this case, my wife had performed a factory reset on her cherished Kindle DX, which she purchased almost exactly ten years ago. After the reset, she couldn’t get any of her books to download. Also: The best Kindles of 2025: Expert tested and reviewedShe wanted to clean the Kindle of all its cruft. Every book she ever bought, up until the last time she powered up the machine, had been on that device before the reset. She thought a factory reset would be the fastest way to start with a clean slate. It was indeed a clean slate. All that was left was a dictionary and user guide, both installed as part of the reset process. And she couldn’t download anything else she wanted on there. I am not an active Kindle device user. I enjoy reading Kindle books on my iPhone, but I’ve never really bonded with Kindle devices. So I haven’t spent too much time tracking all their ins and outs. It took a bit of Googling to figure out that the reason my wife couldn’t download books over Wi-Fi to her Kindle DX is that the DX never supported Wi-Fi. The device did, however, come with full-time 3G cellular support, which is the mechanism by which she had loaded books on the thing throughout the years.

By 2025, most of the major carriers in the US have shut down their 3G networks. Amazon has also phased out support of 3G More

ZDNETHave you ever stopped to look at how many tabs you have across the top of your browser? Is that number so large that you can’t make out the favicons for each of those sites, forcing you to click through them to find the site you need?The frustration described above is more common than you might think. Part of the reason is that many browsers still haven’t figured out how to manage tabs with any level of efficiency.Also: 5 great Chrome-like browsers that put your privacy firstHowever, a handful of browsers make working with an ever-growing list of tabs so much easier that you’ll wonder why you haven’t already made the switch.Trust me — once you’ve experienced real tab management in a web browser, you won’t look back. In fact, after I started using one of these browsers, I couldn’t go back to the old-school method of hunting for tabs in a sea of tiny icons.If that sounds like a frustration you’d prefer to leave behind, read on, my friend, because your tabs are about to get managed.1. OperaI’ll start with the browser that made me leave behind Firefox and never look back. That browser is Opera, and the feature is called Workspaces. With Workspaces, you create categorized spaces (such as Social Media, Shopping, News, and Work) and can open related tabs in those spaces, quickly switching back and forth. You could spend time viewing work-related sites in the Work Workspace and then move to the Shopping Workspace to find a new book to read. Hit the Social Media Workspace and craft a pithy post. Also: 5 great Chrome-like browsers that put your privacy firstWorkspaces can be accessed from the sidebar, and you can create as many as you need. Even better, you can pin specific tabs to specific workspaces. You can also customize keyboard shortcuts to allow you to switch from one workspace to the next without your hands leaving the keyboard. Opera is free to use and can be installed on Linux, MacOS, Windows, Android, and iOS.Best for: Those who want serious tab management, use different operating systems, and don’t mind installing closed-source software.

Those complaints exist because ChatGPT doesn’t always provide the sources, footnotes, or links from which it derived the information in its answers. Here’s how ChatGPT describes the approach: “GPT-4o in free […] More
