Replaced a 2 year old MacBook Pro (w/ 8GB memory) with this one. I heavily use them at work for software development, and at home for personal use. I still feel that it is overpriced for the seemingly little benefit over any windows laptop, but I think it is worth paying since I am realizing the favorable features almost every day, such as the bash terminal and most of the GNU tools every day at work, the light weight, the long lasting battery, the better display. My complaints is that old power adapter can't be used without an adapter, which costs ~$10, and it is missing DVD player/recorder. Also, I wish it has more than 2 USB ports. So far I love the flash storage, which is supposed to make most things much faster compared to regular hard drive.
