Query: NO! As bad as original! Get "Prep" book instead.

I was SHOCKED to find it looks just like the original (by Giles a couple years ago), which had bad ratings. SOOOOO much obscure THEORY that it would take 100 lifetimes to read. And it looks like it has NO Cisco commands at all (like the orig.). I can't understand why the publishers learned NOTHING from all the complaints about the original. NO WAY would I even pay $1 for this!
