Device having integrated interface system

A portable computer comprising:

• a display portion comprising:
• a display housing;
• and
• a display within the display housing;
• a base portion pivotally coupled to the display portion and comprising:
• a bottom case defining at least a portion of a side surface of the base portion;
• a glass top case attached to the bottom case and defining an input surface;
• a touch sensing system configured to detect touch inputs applied to the input surface;
• a magnetic attachment system configured to magnetically retain a keyboard accessory in a predetermined position on the input surface;
• and
• a key sensing system configured to detect, through the glass top case, key inputs to the keyboard;
• and
• a processing system within the base portion and operatively coupled to the touch sensing system and the key sensing system, the processing system configured to:
• register a key input in response to a signal from the key sensing system;
• and
• register a trackpad input in response to a detected touch input applied to the input surface.

An electronic device comprising:

• a display portion comprising a display;
• a base portion pivotally coupled to the display portion and comprising:
• a bottom case defining a side of the base portion;
• a unitary glass top case attached to the bottom case, the unitary glass top case defining:
• a trackpad region along a top of the base portion and defining an input surface;
• and
• a recessed region adjacent the trackpad region;
• a keyboard positioned within the recessed region and comprising a plurality of keys;
• and
• a touch sensing system configured to detect a touch input received in the trackpad region;
• and
• a processing system operatively coupled to the touch sensing system and the keyboard and configured to register a trackpad input in response to the touch input received in the trackpad region and register a key input in response to an actuation of a key of the keyboard.
