Review: Epson DS-40 WiFi portable document scanner
I've always been fascinated by digital scanners; my Dad worked in an industry that allowed him access to some of the newest tech in terms of computing, so I was able to use a full-color (16-bit!) digital scanner hooked up to an early Mac IIci running Photoshop when most people still used computers with 8-bit displays.
My very-old 3-pass color scanner connected to a PowerBook 180c. It took over a minute per scan—and much longer at 'photo' resolutions.
