SONY Vaio Series C, Macbook, or Macbook Pro?

Mac usually are a lot better running, but you not be able to use a lot of programs due to Windows/Mac OS compatibility issues;though this has changed quite a bit and more programs are becoming compatible with Mac. If you want the best quality and are not too worried about some of the compatibility issues, than Mac is the way to go. The Pro that you have listed is only $50 more than the Macbook, so if you do go with Mac, go Pro. Apple has never disappointed me.
