I just got a new MBA. I'll be using it in med school with PowerPoint and other Microsoft applications, so I'm planning on dual booting with windows through bootcamp. I still have time to exchange this for a MBA with 256 GB, but my question is, would 128 GB be enough for both OS X and Windows for what I'm using it for? I'm new to macs too so I really don't know what I'm doing. Thanks!
