Bearing in mind that modst of the computers being sold today are laptops
they do not sit inside the home cowering behind the firewall they are
routinely attached to all sorts of potentially hositile environments,
campus networks, offices, starbucks, airplanes etc and the only security
perimeter they can count on is the one established inside the network
interface rather than outside of it. this mac while a little more widely
traveled than most has 500+ wireless networks which it remembers. making
assumptions abou the security of the nework outside your machine or
expectations for it is extremely dangerous. mMving into the future a
larger percentage of the devices are or are going to be network agile
and the upshot is a rather different take on what constitutes a security
domain.
