Ultra portable devices
User Interface Design Must Be Relevant
Devices become more personal, which creates the need for an ultraportable form factor. People expect their phones to be extremely flexible. They want to work in the train, check their emails in the dentist's waiting room, or during a walk in the woods find out what kind of tree they are looking at.
There is a definite trend toward more ultra portable devices: Batteries are lasting longer, the internet is always available, devices are expected to be compact, yet remain very user-friendly
