There are times that a solution to a problem seems like the most obvious thing to an outsider looking in. People who don't own iDevices tend to think that when someone runs out of space that they can just add some more. "Slap a new micro SD in it and call it good." Well, Steve Jobs and Co. decided against that being a viable option. In ANY of their products. With the massive amount of iPads, iPods, and iPhones out there today, you would think that someone would have mentioned to them that they needed an expansion port. Instead, Jobs decided to leave the device in 2 or 4 flavors. "Oh, they don't like 16GB? Give them 32GB or 64GB and let that be that!" - Steve Jobs
