Hey im really interested in purchasing an 11" macbook air. One a daily basis I only use iTunes, Chrome, Word, powerpoint, and iPhoto. I usually only have itunes, the mail app, and chrome open at one time. The most cpu intensive app I use would have to be photoshop, which I only use a few times a year. I have only about 30gb of files: 20 for music, a few for photos, and a few for apps and a documents. I have an external hard drive which I could easily use for large files. In order to compensate for the small screen I plan on purchasing an external monitor for at-home use. I really like the air because it would be incredibly convenient to bring everywhere I go and i dont need a large screen on the go. I have been reading a lot of people recommend 4gb of ram. Would 4gb of Ram be really necessary for my needs? I never run into problems on my current macbook with 2gb of ram. Additionally, would the upgraded processor really improve performance to a noticeable degree with these apps? And would the upgraded hard drive be really worth it if i only have 30gb of files. Any advice would be greatly appreciated. Thanks!
