I got this camera in Japan. In Japan and Korea it is sold as IXY. In other parts of the world we know it as IXUS. You can ge the tech specs online so I will not go into that. This thing is simply marvellous. About the size of a credit card, It has 3x optical zoom (11x digital zoom)...though I would have preferred more of optical zoom. Any way I am no wildlife photographer or the paparazzi. I like to get quite close to my subjects and click away. With a 512 Mb Toshiba SD card, I have been clicking pics everyday since I came to China, its not even full (pics bein standard 1024 x 768 format).
With a USB cable to transfer data to the PC, storage size is no longer an isue with me. Microsoft XP an even my Ubuntu Linux, auto detects the camera and does what is needed. After that you can numerous things with Picasa.
My review....a good value formoney and does not disappoint at all on qality contrary to popular belief.
