We’ve had lots of software guys join us on the Mac Power Users but I’ve always been interested in talking with a hardware guy. Geoff Barrall describes himself as a serial entrepreneur. He’s founded several companies that got successful hardware products to market including the Drobo and Transporter. Geoff is also a big Mac nerd like the rest of us. This week Geoff joined us to talk about how he uses his Apple gear and what’s involved in developing and releasing hardware devices.
