Casino Royale - Ian Fleming

Just finished rereading Ian Fleming's original novel, which was the basis for the recent movie.  I've had the paperback since I collected all of the 1960's paperbacks of the Bond novels in high school (this 1963 edition set me back 40 cents 25 years ago and is now valued at around $19) and hadn't read it since then.
On rereading it, I realized that my impression of the movie's Bond as accurate to the book wasn't quite right - Bond's character as cold, ruthless, and new to the job is not really in this book all that much.  He's a  veteran of WW II (the book is set in about 1952) like everyone else, and cold and ruthless to an extent, but surprisingly naive about his opposition and sentimental about Vesper when they go on their vacation after defeating Le Chiffre.  He already has the polish that the movie's Bond lacks at the outset (his obtaining it inexplicably quickly as he heads for the casino is one of the movie's weaker points).  None of this is a negative about the book or the movie - just some differences.
The book also struck be as a bit dated - not just in how women were treated but in overall tone.  It wasn't quite what I remembered, but then, it has been a quarter of a century or thereabouts since I read it last.
