Factory reset and ready for use!
The S100 is its built-in GPS unit, similar to that used in the PowerShot SX230 HS 'travel zoom'. This not only allows you to tag images with the location at which they were taken, but also includes a logger function that can keep track of your movements.
In terms of external design, the S100 gains subtle finger and thumb grips, which should reduce the chances of it slipping from your grasp if you're not paying due care and attention. This is not the shiny silver of the Elph / Ixus series, but a darker, matte-finish look.
This camera comes with a battery and ssd card (inside the camera), battery charger, and a pouch. It does not come with cables or in original box.
