WayneShaw, you missed my point,
99% of people using computers out there do no know what Linux is or for that matter what CakePhp, PHP, MySQL, Centos etc, etc, etc...........
As I mentioned earlier, they just want to turn on their computer and have it working for them. Anyway that's just my take.

You left out UNIX which Mac OSX and iOS is based on and certified as such. Linux is too.
