An anonymous reader writes: Microsoft's Surface 3 may be coming to an end. Brad Sams at Thurrott.com reports that many versions of the Surface 3 are listed as being out of stock in Microsoft's online store, with no expected availability. He notes that the only version in stock online is the version with 2GB RAM/64GB storage/LTE. There's more availability in-store, but stock appears to be limited overall. What this generally means is that manufacturing is slowing down or going to stop entirely. In a statement, Microsoft said: "Since launching Surface 3 over a year ago, we have seen strong demand and satisfaction amongst our customers. Inventory is now limited and by the end of December 2016, we will no longer manufacture Surface 3 devices." It's possible a Surface 3 successor is right around the corner, although Ars Technica notes "there hasn't even been the merest hint of a rumor about such a device." The Surface 3 is being powered by a Cherry Trail Atom processor, which hasn't seen a major upgrade or replacement since they were released in the first quarter of 2015. "Without new processors, there's little reason to update the Surface 3 line," writes Ars. Microsoft could equip the Surface 3 successor with a Core M processor, but the implications of that decision would likely cause the device's price to shoot up or cause the device's quality to significantly decrease. Microsoft may simply abandon the segment entirely and focus strictly on the Surface Pro line.
