I prefer the current "Larger" sized version of the NEC.
Text is a little larger, the book stays open easier on my desktop
(actual real desktop, not what's "inside my monitor" desktop
...),
and since pages are larger, each page holds more text - so book is less bloated.
Now to get Grainger to follow... images are easy to see, but that <4 point text is quite blurry for me after doing some "Marathon" CAD / PC work!
Funny thing about what has been mentioned by others in regards to larger text (at least funny to me):
If my eyes keep progressively getting worse, I would totally support the printed hard copy version of 2008 NEC using 24 point bold Sans Serif fonts! Something in an Arial or Swiss flavor will be fine.
Weights of Character sets would increase in a linear fashion per every other code cycle - meaning that by 2014, font size would increase to 48 points, and by 2020, font size would be at 72 points!
After that, the term "Mr. Magoo" applies to me - and as a result, it's time for "The NEC On Audio Tape" - or more like my CD version of the NEC would contain Digital Audio only!
Just give me a copy with individual letters cut out of Magazines, glued to blank paper - similar to the "Stereotypical" Kidnappers' ransom notes in Movies.
(I used to have a font that had this look, and man I sent out some crazy looking memos!).
