Get a Mac.
A MacBook Air will run you $1,000 and a MacBook Pro will run between $1,200 - $2,500 depending on size. I switched from PC to Mac last January and bought a MacBook Pro 15". I have been very pleased with my decision to switch.
Although, the Windows 7 laptops I was looking at were a couple hundred less than the MacBoo Pro, and I'm sure they still are, I was impressed by its build quality, the Operating System's look and feel and the availability of the applications I needed.
Another big factor in my decision was the experience I had with the number of Windows laptops I have been given at work over the years.

None of them even come close to my MacBook Pro.
