Smartphones will continue to grow in market share as service providers push smartphones to generate additional revenues from data packages, while consumers continue to pull on the demand side by requesting more features and higher data speeds. A great example of this is the latest iPhone 4S. iPhone 4S users take eight megapixel pictures and record 1080p video. To store this digital content, the iPhone 4S contains up to 64 GB of memory. Future phones will contain 64 GB to 128 GB of memory or more. Users will fill the memory with videos of soccer games, spring break, birthday parties, or, let's face it, actions that should not ever be recorded or broadcasted (like spring break). Pictures and video will be stored on USB 3.0 hard drives for posterity, but only after being transferred to a PC first. Will LTE, 3G phone networks and the Cloud be sufficient for moving these memories quickly and storing them forever? It's unlikely. The amount of data created will be larger than the data capacities of LTE or 3G networks (like when AT&T's networks slowed down with the success of the first iPhones). The cost of storing data infinitely on the Cloud will remain high.
Users will need and want to upload their content to PCs or a central storage device for safekeeping. They will want to download their personally created or purchased commercial digital movies and content on to smartphones. If you own an iPhone today or ever have upgraded from one iPhone to another, you know exactly how many hours it takes to move your media across. The speed of USB 2.0 isn't going to be fast enough. The table below shows the relative speed and complexity of the various generations of USB specifications.
