Computers used to require entire buildings to operate. Now they fit in our pockets. Similarly, factory-size electronics manufacturing is approaching a contraction. Want proof? Look at that $50 printer on your desk and imagine, instead of using it to spit out a hard copy of that thank-you note, that you used it to print some digital memory. Not enough memory to power a laptop. Think smaller, like smart tags to inventory all the crap in your workshop.
