I'd attribute it to the software. iOS and Android are clearly meant to coexist with and not supplant a more traditional OS. To me, the dangerous precedent is that this new ARM computer comes loaded with "Windows", a label which connotes a more traditional OS, yet it can only run apps from MS's app store and cannot be booted into Linux. Yes, this is a slippery slope argument given that MS also provides the x86 version which can do all of those things, but I think the distinction will be lost on the general public.
