I have had my MacBook (aluminum casing) for a year now and I love it! You will not be sorry, it is more than worth the money. My last laptop was a Dell and I thought nothing could be better, that is, until I got my MacBaby.
If there is an Apple store in your area you can take a one-hour class (free) and they show you how to use your new Mac (whatever you did on the Dell, this is how you do it on the Mac, kinda' thing). There are also videos on the apple.com site that are helpful.
Have fun and welcome to the Apple Family!
