LOL! Great ad

She's hot!
Still, Macs are better (Screen quality, hardware quality, OS quality, application quality, etc.). PCs are more affordable to get, but in the end more expensive when you add everything you need to get things done. Unless, you are a proud pirate
In the end, it's a personal choice. I like Unix and Unix like systems
One thing I hate about Windows Vista is that when you install an application, you seriously have to monitor it's services to make sure it doesn't slow down the system. I have to check my services from time to time (stopping some and changing them from automatic to manual) to keep my Windows blazing fast. With Unix systems, I don't have to do that. Windows 7 does do a good job at fixing this. I have heard good and bad things about later build releases of Windows 7. Still, it's in beta and miracles can happen. Windows Live is getting better each day. Props to the Live team!
To me, it's all about waiting. PCs if you don't have the cash for a full system, you can still get a decent one for cheap and then pay your way up to what you want. Still, on the other had, you can buy Macs for cheap at applepalace.com and other sites on the web and locally from shops at a great deal.
It's all about what you want and when you want it. Just make sure to check the Windows sticker on the laptop before purchasing it.
