I've had my Macbook for 5 days now and I'm extremely happy with the purchase. The Apple online store had them refurbished for $899 or I could have bought a new one for $1199. I looked at another dell and with a warranty they would have run me $1200. I couldn't really see what a PC could offer me besides windows Vista.
What I did was buy a refurbished Macbook with a warranty, 160GB external drive, and a usb hub for $1200. If I bought anything new I would have paid much more for all of it. I couldn't be happier. Now I just have to find a software hook up. Now I am able to have my entire music collection on my hip since I'm not dealing with an overpacked hard drive. It's been a long time coming.
So Mac or PC? I would say Mac there are so many things that are easier. Things aren't buried way deep in a directory you don't know that exist. It's far more intuitive to way I think. There are only a few keyboard shortcuts that are different. It's just beautiful to gaze upon as well.
