Yoggie's mini "security computers" have been at the disposal of PC users for some time now, and it looks like the company has now finally decided to give Mac users a taste of the completely hardware-based security solution. That comes in the form of both Mac-friendly versions of Yoggie's Gatekeeper ExpressCard and its Gatekeeper Pico USB stick, each of which are "full-blown" Linux-based computers in the own right, and include a slew of applications that promise to both increase security and take some of the load off of your laptop or desktop. What's more, it looks like Yoggie is also giving Mac users a slight discount for their patience, as the Gatekeeper ExpressCard and Gatekeeper Pico are now available to pre-order fro $150 and $119, respectively, a 20% discount compared to their usual price, and their PC counterparts.
