The Apple Keyboard is a keyboard designed by Apple Inc. first for the Apple line, then the Macintosh line of computers. Dozens of models have been released over time, including the Apple Extended Keyboard. There are currently two keyboards offered by Apple: a full-sized version using USB, and the Apple Magic Keyboard, which connects via Bluetooth and omits the numeric keypad of the full-sized model.
Both share a similar look and feel, based on a very thin aluminum chassis and laptop-style low-profile keys, sitting much closer to the tabletop than traditional keyboard designs.
The heftier design solidified visually the power performance embodied by the upgraded Macs. Aside from weight the main difference was the significantly thicker frame width. It was the first keyboard to be sold separately from the system, giving the customer a choice of the basic or advanced keyboards offered by Apple.
