Apple did NOT invent the pentalobe screw. SONY used them years before, as did others, especially in industrial uses. Pentalobe screwdrivers were available commercially, so the "trying to keep the average Joe/Jane from opening the phones" is not true, or at least was not effective.
Also, lots--if not all--of screw types are applied with powered drivers. This is the 21st century in case you hadn't noticed.
Magnetized screwdriver heads. It's a thing.
