The Mac Pro is currently the only system capable of using internal PCI Express cards, although companies like Magma have been providing laptop users with external ExpressBox solutions for years. Unfortunately, those require an ExpressCard slot, which is now long gone from the MacBook Pro – so why not bring this ability to all Macs featuring the Thunderbolt port? As it turns out, Magma is indeed working on a new Thunderbolt Expansion Chassis, so our prayers will be answered soon enough.
