Hey everyone!

I am totally new to the Mac computer and I am planning on getting one is about a month. Anyways, I heard the new model is release and I was just wondering when they will be available for purchase is North America. Also, what is the difference between the old and new models?

Now!
I just picked a 24" 2.66GHz model at my local Apple store.

& The difference is performance changes, price, and little physical tweaks such as the shape of the stand.
