The Greek Geeks carried around stone balls and cones and such. From the seventeenth century to the 1970's there were slide rules. The 1970s aand 80s saw pocket protectors and HP calculators — HP41s, 48s etc (Sorry TI fans, TI calculators only convey wannabe status). Now if you carry a laptop or whatever, you'll be confused with a yuppy! What can the modern geek carry to set him/herself apart?"
