I once had a plastic white Macbook 6 years ago, but it was stolen... Impressed by the qualities of Apple notebooks and the Macintosh OS, now I have saved some money and would love to own a Macbook again The Macbook will be my only computer. It's mainly used for software development, running Windows/Linux virtual machine, editing photos in Adobe Lightroom, and watching blu-ray format movies. No gaming or Photoshop. In terms of budget, my first choice is Macbook Air 13" with i5-CPU, 8G-RAM and 128G-SSD. However I have some concerns. How much space is left besides OSX, VMware, and Windows 7(64b)? How does MBA perform when running a parallel Windows or Adobe Lightroom? Thanks for your advice.
