A.H.
I was always a dell girl until I got a mac. It took a week of getting used to, but I will NEVER buy a PC again! Mac's in the end are a lot easier... they make it so simple to use. And you don't get viruses like you would with a PC. They automatically hook up to any wireless in the area. In fact, my mac prefers to pick up the neighbor's wireless signal. The MacBook is the least expensive, but for my daily use I will never have to get more memory or upgrade to the more expensive one.
Good luck computer hunting!
