hell, forget windows. Let's look at phones! Android phones rare ever get patched. A hardware firewall in front of them seems very smart!
If you are concerned with security to the point that you are carrying hardware to put in front of your phone, wouldn't you more likely just get an iPhone?
The article implied that iPhones were just as easy to force to his AP as Windows or Android devices.
The point was that they are patched regularly. The carriers can't block it and Apple really annoys people who hold back. Apple takes security seriously in a way that Google cannot because of how they treat the ecosystem and carriers.
Google capitualated, Apple didn't. Apple said - you want our phone, you'll do it our way.
The carriers told Samnsung, LG, HTC, etc (I'm sure Google wasn't even part of it) you want us to carry your phones, you'll do it our way, or we'll find someone who will.
