The biggest change in this latest refresh is a new processor, but Wall Street Journal says they "didn't even notice a difference" between last year's model and this one. And while a bump in speed would normally mean a drop in battery life, Macworld notes the MacBook Air is "able to maintain its superior battery life." However, critics hoped for a little more from the screen -- it's not a Retina display like the one on the MacBook Pro, but PC Mag still says "the screen looks just as good as the last time we saw it."
So while the newest MacBook Air may not have a Retina display, it does have a slightly more powerful processor that doesn't ding the battery life, and it's $100 cheaper. The result is a compact, powerful and productive laptop that will suit many users' needs.
