Hey everyone, I've had my eye on the Macbook Air ever since they first came out in 08, but the new refresh sealed the deal for me. I'm just having trouble figuring out what I really need. I am a Professional Writing major, so this machine would primarily be for writing on the go. I already have a 21.5 iMac that I love dearly and can use for games and photography. A couple things I'm having trouble with: Since this is really going to only be used for internet surfing and writing, do I really need the 4GB of RAM? I'm leaning towards the 13 inch because of the longer battery life and the bigger screen but I'm curious to hear from current owners of both models. What do you think? What were the deciding factors for you? Are you happy with your choice? What do you feel was your biggest sacrifice? On a slightly unrelated note, what kind of setup do you guys have for your Air? I really like the look of the BookArc but on Apple's site it specifically says it's only compatible with the first generation Air, which means to me that it isn't compatible with the second generation. Does anyone know of a similar stand? I want somewhere to put my Air on my desk so it isn't just lying around in a college dorm room, if you know what I mean. Thanks so much for your help!
