One bit of technology that I can’t live without at the moment are my usb sticks.
i have 4 of them that contain my work ‘life’
Probably not the wisest idea I’ll admit, and if they were to fail I’d be up sh*t creek well and truly, but they’re easy to carry around. Each one is labelled with what is on it, so I can just grab, stick the little sucker in and go.
