A question for Matthew Polly,
Hi MR Polly I real want to buy the book but then I saw something about the book:
Hardcover are 656 pages and softcover are 672 pages...can you explain that?
1) The softcover shouldn't be available yet. Softcovers usually come out a year after the hardcover. 2) To answer your implied question: it will be exactly the same material in both version. There won't be any changes. 3) Softcovers are usually a bit smaller in size (dimensions) than hardcovers, so as a result they tend to be a few pages longer. 4) It'll probably be about US$10 cheaper than the hardcover, so if you are willing to wait a year it'll save you some money. 5) Authors generally get paid about US$3 for every hardcover sold and $1.25 for every softcover. So you spot me US1.75 and get the softcover if you'd like :)
