Ordered my first Mac

I've never had a mac computer, so I am a little worried about this purchase...but I've been wanting to switch for a while...I'm sick of my computer always crashing and freezing up. The last time my PC crashed I had to use linux to actually fix the thing.
Anyways, I ordered the new iMac with the 24", 2.8ghz, and 2gb of RAM. A big investment, but I'm sure it will all work out for the best. I am the creative type and am told that macs are good for creativity. It should arrive sometime next week before I head back to school so I'll be sure to review it here for everyone.
Just hope the whole mac thing works out for me.
