I use a 250GB Macbook, and it's hard drive is full. I'd love to switch to the 11-inch, 128GB Air but it seems like I can't give up the storage space (and I don't want to pay the extra $300 for for the 256GB option). iTunes takes up the majority of my hard drive, chock full of music and iOS apps. Will iCloud help my problem? Will the "cut the cord" iOS5 features help? Any other solutions that would allow me to live comfortably with even a sub-100GB hard drive so I can switch without stress?
