My wife is deciding on a 13" MBA configuration for her upcoming MBA coursework. 8gb of ram seems obvious. Are there any good guides or rules of thumb to best determine space or speed needs? She plans on using mostly Internet and MS office (maybe onenote which will require her to constantly run fusion or parallels). She won't be storing any music or video on it. Is a 256gb hard drive enough? She tends to never restart her current windows laptop and prefers to instead hibernate/suspend until they become too slow and unstable at which point a restart is required. Because of this, should she consider getting the faster 1.7 Ghz over the 1.3 processor?
