Today, I will be ordering a MBA as my main machine. I recently tried out 4 late 2013 13" MBPr's and all had yellow tint in different parts of the screen, image retention, scrolling lag when I set scaling to above best for retina, and the online website that I use for work looked fuzzy. For now, I giving up on retina displays. I decide to purchase either the 13" i5 1.4/8/256 or the refurbished i7 1.7/8/512. The price difference is $140. I plan on using it for 3 years. I will be using the MBA for the following things: 1. Internet 2. Work 3. Microsoft Office 4. Bootcamp Windows 8.1 Pro Also I have few questions on the MBA: 1. Did Apple finally fixed the latency times when pinging to the router via wireless? 2. Where can I download the screen calibrated profiles if I get a Samsung or LG screen? Please recommend which MBA is the right one for me?
