I think the big difference here is that we get the potential to put multiple disks on a single usb device. From the technicians perspective I'd like to rid myself of the big stack of cd's i have that i use to install windows, or run diagnostics, or any of those things. I remember thinking to myself last year, man if only someone made this. And low and behold here it is. I may have already talked my boss, (he's the owner, I'm the Technician Manager.) Into pledging for 5 32 GB models. (Something like 1,100 dollars ish.)
