This chips promise and I thing they could sell extremely well, nevertheless Intel sill be selling them at high prices. A lot of devices including the Surface Go 1 could already feature a "Core-M" type of chip instead of pentium types or other chinese devices some celeron or pentium or atom type of devices. But that if Intel did not charge a premium for them, so the core M did not sell.
Here we're talking about an Atom chip + 1 core "core type" which means it won't be much better than a Core-M but has an updated graphics and better standby consumption. All in all, every brand would better off TDP down AMDs which would perform better, better graphics and just a small hit on battery life, which most people wouldn't mind.
