Honestly using Skylake is fine because there isn't really much of a difference between it and Kaby Lake, and there isn't likely to be much of a difference between it and Coffee Lake and Canon Lake. Intel's hit such a plateau that you could even throw haswell based chips in there and barely notice a difference, if at all. Not that it would matter much on a machine that's basically just a glorified web terminal, and honestly it's a space that AMD's Bristol Ridge would have done exceptionally well in. If anyone would have ventured to use it in a chrome book, as opposed to cheap, crappy, huge, and stripped down commodity laptops with single channel memory, and 5400 RPM spinning disks.
