1) Haha, well the "current major mobile threat" jab was more tongue in cheek, and you're right - it's the "No iOS Zone" vulnerability. The citation is the following: RSA conference presenter SkyCure discussed the possible vulnerability [0] in iOS 8 that _could_ allow iPhone users with iOS 8 to be victimized by the equivalent of a DoS attack. And, the org has worked with Apple and iOS 8.3 likely fixes the issue.

2) However, while I wasn't making an argument per se, more just thinking out loud about architecture choices, especially when they "mimic" systems that are not for the same purpose, I do believe that is a small part of the problem when it comes to mobile security as pertains to phones. And, maybe I'm also thinking that with that in mind, there might be room for a whole separate set of protocols and methods for interacting with the Internet (or a reasonable facsimile of it) from your phone, which is not a PC :-)

I understand your motives, but the problem with your argument is that youre telling us what a mobile phine shouldn't be (no internet, no TCPIP even, and reading a bit between the lines perhaps no GPS or Wifi even). But to usefully describe a thing you need to say what it is and what it does, not what it doesn't do.

Yes, I suppose I left out the important part where I should turn around and state what I think the actual alternatives are, and if they don't exist, propose them :-)

I'm still getting my feet wet with this critical thinking exercise, especially where an exchange of ideas is required to hone my own! I'll have to come back to this one...
