Yeah, I read about the updated specs/requirements. This is very typical Microsoft - introduce something (somewhat cool) and then cancel or change it afterwards for whatever reason, pissing of customers. Now that they finally quit their mobile phone business, I suspect a lot of Lumia models will be dropped out the update train as well.
The announcement happened few months prior to the expected Redstone update, aka Anniversary Update. So it might be that devices with 1GB will not receive this update and are limited fo security updates from the Threshold branch?
Keep in mind that Linx/Lamina was never Windows 10 supported by the vendor, along with many other Windows 8 low-end tablets. Another sneaky Microsoft tactic to announce Windows 10 and promote it as a free update and at the same time promote dirt cheap Windows 8 products that are not actually compatible.
