It's been a big year for Windows running on Arm chips, something that Microsoft and Arm chipmakers have been trying to get off the ground for well over a decade. Qualcomm's Snapdragon X Elite and X Plus are at the heart of dozens of Copilot+ Windows PCs, which promise unique AI features and good battery life without as many of the app and hardware compatibility problems that have plagued Windows-on-Arm in the past.

Part of the initial wave of Copilot+ PCs was a single desktop, an $899 developer kit from Qualcomm itself that would give developers and testers a slightly cheaper way to buy into the Copilot+ ecosystem. Microsoft put out a similar Arm-powered dev kit two years ago.

But Qualcomm has unceremoniously canceled the dev kit and is sending out refunds to those who ordered them. That's according to a note received by developer and YouTuber Jeff Geerling, who had already received the Snapdragon Dev Kit and given it a middling review a couple of weeks ago.

"The launch of 30+ Snapdragon X-series powered PCs is a testament to our ability to deliver leading technology and the PC industry's desire to move to our next-generation technology," reads Qualcomm's statement. "However, the Developer Kit product comprehensively has not met our usual standards of excellence and so we are reaching out to let you know that unfortunately we have made the decision to pause this product and the support of it, indefinitely."

Qualcomm's statement also says that "any material, if received" will not have to be returned—those lucky enough to have gotten one of the Dev Kits up until now may be able to keep it and get their money back, though the PC is no longer officially being supported by Qualcomm.
