When I first started using cell phones, I always enjoyed the clamshell or flip format. I found these types of phones very useful and cool because you could answer and end a call just by opening the flip. I never really liked the candybar form factor. That is until SonyEricsson released their Cybershot line of phones, which could easily double as a point-and-shoot camera. Currently, the model that most manufacturers try to emulate is the iPhone. None have been very successful. You either end up with an iPhone clone or a Crackberry-like device. Philips is trying to revive the flip phone format. Was this revival successful?
