Double function, I like it. LG has launched the LSM-100, which is a mouse that double as portable scanner. I’m not sure if this stuff is actually comfortable to use or not, but as a PC mouse, it’s pretty much done the job. However, on the flip of the coin side, the scanner function is pretty questionable. It has 5 LED with 300dpi sensor, but no idea how good the result of the scan will be.
