I have had my 15" MBP for about a week and a half. Never really had first hand experience with a Mac before that. So, you are like me a couple of weeks ago.
All I can say is; don't be frightened. The switch from Win to Mac is very light. Watch a few of the Win->Mac switching movies on www.apple.com and you are set to go.
Yes, you can go deeper if you want in OSX, but in an hour you will already be familiar with the few OSX oddities that set it apart from Win. From there on it's up to you how hardcore you want to go in OSX.
