Apple Thoughts: Hey Switcher, Need Some Help?

"You've caught the buzz. You've been watching the weather, seeing how the wind blows. You've moved or you're moving to the Mac, because Windows blows. Where can you get the advice you need to help you with this transition?"

Several good choices, the best one being "Switching to the Mac: The Missing Manual" by David Pogue in my opinion, mainly because it has the most up-to-date information and covers pretty much all you need to know when switching. Well, if you are switching to Snow Leopard. If you are switching to an older version of OS X, then try one of the other books listed.
