Pentalobes have been used in MacBook Pros since 2009.
It's not that hard to replace them, you can pick the screwdriver for the Retina MacBook Pro and Airs for $12.95 from iFixit or as part of a set of different drivers. You might even find it cheaper on Amazon.
What I meant to convey was that you have to specifically go out and buy a pentalobe screwdriver for the sole purpose of opening your mac, whereas with the other tools, I (along with many others) already have them.
