Hmm perhaps you should buy one of the competing cheaper laptops that have no built in encryption then?
It's apple that does something exotic, breaking industry standards, and then calls what should be standard by some new name for marketing reasons. Same with how lots of people think a "retina" display is some wonderful apple invention and not just a standard samsung panel.
No, really, does anyone actually enjoy using cheap laptops? The only use case I think they would excel at is as a thin client for VMWare/Cisco virtualization solutions, or as a barebones terminal for Linux distros (at which point anything with a keyboard works for you).
Anyways, if laptops do security the same way laptops do touchpads, I would not be excited to depend on that. At all.
