I have spent days reading and searching this site for the answer but still have a question. Im looking at my first Mac purchase in the next few days and trying to decide if the MBA 13 is still a good buy. I plan to upgrade to the I7, 8GB, and 512GB. My use is personal and work from home using Parallel or Fusion. I'm moving from a Toshiba 17" laptop the size of a small ship. In the Apple Store, the MBA 13 looks like it would do the job, but I'm concerned about screen size and website readability. It appears that when visiting a website they stay within a certain "frame size" even if you maximize the screen. There is always lots of space on the screen not being used by the site. Do you have better readability if you go with a rMBP 15? A loaded MBA with Apple Care is approximately $2,500 with the rMBP 15 a few hundred more. This is why Im asking if the MBA still a good buy at this time. Appreciate any comments.
