Logitech announced a new mouse last week. A company rep reached out to inform Ars of Logitech’s “newest wireless mouse.” The gadget’s product page reads the same as of this writing.

I’ve had good experience with Logitech mice, especially wireless ones, one of which I'm using now . So I was keen to learn what Logitech might have done to improve on its previous wireless mouse designs. A quieter click ? A new shape to better accommodate my overworked right hand? Multiple onboard profiles in a business-ready design?

I was disappointed to learn that the most distinct feature of the Logitech Signature AI Edition M750 is a button located south of the scroll wheel. This button is preprogrammed to launch the ChatGPT prompt builder, which Logitech recently added to its peripherals configuration app Options+.

HMD has been known as the manufacturer of Nokia-branded phones for years now, but now the company wants to start selling phones under its own brand. The first is the "HMD Pulse" line, a series of three low-end phones that are headed for Europe. The US is getting an HMD-branded phone, too—the HMD Vibe—but that won't be out until May.

Europe's getting the 140-euro HMD Pulse, 160-euro Pulse+, and the 180-euro Pulse Pro. If you can't tell from the prices, these are destined for Europe for now, but if you convert them to USD, that's about $150, $170, and $190, respectively. With only $20 between tiers, there isn't a huge difference from one model to the next. They all have bottom-of-the-barrel Unisoc T606 SoCs. That's a 12 nm chip with two Cortex A75 Arm cores, two A55 cores, an ARM Mali-G57 MP1, and it's 4G only. Previously, HMD used this chip in the 2023 HMD Nokia G22 . They also all have 90 Hz, 6.65-inch, 1612×720 LCDs, 128GB of storage, and 5,000 mAh batteries.

As for the differences, the base model has 4GB of RAM, a 13 MP main rear camera, an 8 MP front camera, and 10 W wired charging. The Plus model upgrades to a 50 MP main camera, while the Pro model has 6GB of RAM, a 50 MP main camera, 50 MP front camera, and 20 W wired charging. There is a second lens camera on the back, but it appears to be only a 2 MP "depth sensor" on all models.

History might consider the most important aspect of Ubuntu 24.04 to be something that it doesn't have: vulnerabilities to the XZ backdoor that nearly took over the global Linux scene .

Betas, and the final release of Ubuntu 24.04, a long-term support (LTS) release of the venerable Linux distribution, were delayed , as backing firm Canonical worked in early April 2024 to rebuild every binary included in the release. xz Utils, an almost ubiquitous data-compression package on Unix-like systems, had been compromised through a long-term and elaborate supply-chain attack, discovered only because a Microsoft engineer noted some oddities with SSH performance on a Debian system. Ubuntu, along with just about every other regularly updating software platform, had a lot of work to do this month .

What is actually new in Ubuntu 24.04 , or " Noble Numbat ?" Quite a bit, especially if you're the type who sticks to LTS releases. The big new changes are a very slick new installer, using the same Subiquity back-end as the Server releases, and redesigned with a whole new front-end in Flutter. ZFS encryption is back as a default install option, along with hardware-backed (i.e. TPM) full-disk encryption, plus more guidance for people looking to dual-boot with Windows setups and BitLocker. Netplan 1.0 is the default network configuration tool now. And the default installation is "Minimal," as introduced in 23.10 .

Qualcomm’s Snapdragon X series of chips promises to be the company’s first that can go toe-to-toe with Apple Silicon, and the PC ecosystem is reacting accordingly . Microsoft reportedly plans for the Arm version of its next Surface tablet to be the flagship, and major apps like Chrome and Dropbox have recently released Arm-native Windows versions for the first time.

Ahead of the chips' launch late this year, Qualcomm announced a new lower-end model destined for cheaper devices. Dubbed the Snapdragon X Plus, it shares a lot in common with the flagship Snapdragon X Elite .

The Snapdragon X Plus includes 10 CPU cores instead of the Elite’s 12, though the more noticeable change is its lack of support for clock-speed boosting; the chip’s 3.4 GHz base frequency is as fast as it goes, where the Elite chips can boost two cores to 4.2 GHz and one core up to 4.3 GHz, depending on the specific model. Qualcomm also rates the X Plus’ integrated GPU at 3.8 TFLOPs, down from the X Elite’s maximum of 4.6 TFLOPs. Aside from those high-level FLOP numbers, we still know very little about how the GPU will be configured; we also don’t know the ratio of “big” and “little” CPU cores.

“Gadgets aren’t fun anymore,” sighed my wife, watching me tap away on my Palm Zire 72 as she sat on the couch with her MacBook Air, an iPhone, and an Apple Watch.

And it’s true: The smartphone has all but eliminated entire classes of gadgets, from point-and-shoot cameras to MP3 players, GPS maps, and even flashlights. But arguably no style of gadget has been so thoroughly superseded as the personal digital assistant, the handheld computer that dominated the late '90s and early 2000s. The PDA even set the template for how its smartphone successors would render it obsolete, moving from simple personal information management to encompass games, messaging, music, and photos.

But just as smartphones would do, PDAs offered a dizzying array of operating systems and applications, and a great many of them ran Palm OS. (I bought my first Palm, an m505, new in 2001, upgrading from an HP 95LX.) Naturally, there’s no way we could enumerate every single such device in this article. So in this Ars retrospective, we’ll look back at some notable examples of the technical evolution of the Palm operating system and the devices that ran it—and how they paved the way for what we use now.
