Welcome to the world of apple. It's addictive. I currently have a 13.3" MacBook pro, iPad 64gb, 500gb time capsule and my wife and I are about to upgrade to the iPhone 4 from the iPhone 3G. We also had an iMac 20" previously, but changed to a laptop. I will be changing the MacBook for a Mac mini server if they refresh them with hdmi output, then will plan to get another iPad at some stage. :)
I don't use mine for gaming, but vmware and parallels are both great if you 'have' to run windows. I set mine up with boot camp once, but just couldn't bear to run windows on my beautiful Mac, so deleted the partition. I have to support windows on a daily basis, so running osx at home is a pleasure and a change.
Enjoy!!!
