I'm about to buy a Macbook Air. This will be used mostly during travel and when working outside of the home, or on my standing desk in my home office. I have a Mac Pro in my home office at a seated desk that I use for photography and more CPU/GPU intensive work. The MBA is strictly for email, web browsing, iWork, some audio recording (Garage Band) and other basic stuff. I won't do photography work, video editing, or play games with it. I'm trying to decide whether to get the i7 or i5. Money isn't the issue; battery life is. I've read conflicting reports on whether there's a difference between the two; some article suggest the i7 actually gets better battery life, others suggest worse. There are several threads about this over on Apple's forum, and there's one particular guy that insists that the i7 gets 3 hours less battery life than the i5. (He does seem like kind of a crackpot, though.) Does anyone have firsthand experience with this? What's the consensus at this point? Battery life is my #1 criteria for this machine. If the i5 gets better battery life, I'd be inclined to go with itespecially since I won't be doing any CPU-intensive tasks. I will be maxing the storage (512 GB) and RAM for what it's worth.
