I'm about to buy a new Macbook. I'm debating between the Macbook Air 13' 1.3GHz with 8GB RAM and the new Macbook Pro 13' (retina) 2.5GHz with 4GB. I'm a web developer and spend most of my time on terminal and a text editor. I have a lot of tabs open on Chrome/Safari all the time. My current Macbook Air has 8GB and I'm usually using more than 4GB. But, apparently Mavericks is better with memory management so maybe I'd be ok with only 4GB. I'm not sure. What do you guys thinking? Have you been using Mavericks with 4GB? How is it? The Macbook Pro processor is much better than the Air. And it comes with a Retina display swell. Any help is much appreciated. Thanks.
