Ob:
I have a soft '08 & 'o5 NEC at office, and a set that are either 'home' or in my bag for the courses I teach.
I have '05 & '08 on CD in my laptop, and at the office. (Laptop goes to school too)
'05 & '08 Handbooks are in office.
'05 Handbook is on my laptop....waiting for the '08 (any day now)

Collections date back to '81 home, and further back at office. Through in lots of 'other' publications, changes, trade info, etc.

As to when I was just an EC, each truck had a soft cover current NEC, and my EC shop had copies also.
Soft covers took a beating in the trucks, but handy when needed.

As an AHJ now...soft cover in breifcase or Twp car suffice, Handbook and CD in office.

CD's make life real easy, as long as you have a PC/Laptop handy, plus the print option is nice.
