great idea just hope the pages don't get pulled out.....
That's my "working copy". I've got another for show/reading or what have you. Someone brought up this idea to be able to lay flat and read while they were working, and I bought 2, so I figured I'd give it a whirl.
That one I will write in, take notes, use for reference. There was some deal going on at Barnes and Noble where if you bought a few books you got a deal, and I had a gift card I got as well, so ultimately the second book ended up only costing me (money from my pocket I wouldn't have spent on a second copy, anyhoo) ~$10-15, plust $5 for the spiral binding at Kinko's.
