the s8300 is one of the first touch screen mobile phones that also features a slide out keypad. this allows users to interface with the phone by using the touchscreen to navigate the touchwiz interface, as well as the fallback of an 'old-tech' keypad for software that either does not support the touchscreen, or for users that are not comfortable with the touch interface for phone calling and text entry. having a slideout keypad also means that the screen is not obstructed with an onscreen keyboard/pad when entering text or other information into the phone.
