Well frankly I wouldn't even pay $400 for the top spec SG because it feels slow now, and can imagine getting one in a year even for free.
They're all within the category of detachable PCs which is what consumers mostly care about when considering so my comparison is actually spot on. For practically weighing the same, a slightly bigger screen estate is an advantage so far as they're all portable. And Dell and Lenovo's refurbished PCs can be purchased with equal warranties as their new laptops, which far surpasses anything MS or anyone else has to offer.
For a $700 tablet that barely has any productive function due to glaring hardware limitations, I'd expect not core M, Y, Pentium "Gold" but at least an i3-8145U, so that I can actually use it for at least some multitasking and media consumption which I presume is the targeted use case.
Essentially the SG shares the same number of flaws as the current influx of WoS devies with QC850, the most critical one being that it struggles to run x86/64 programs. Because then people can just look over to much cheaper Android tablets or iPads that are still light-years ahead in terms of mobile productivity experience.
