WOW!!! i just looked up this software and its amazing. you can take a picture of a document send it to scanr & it will send it back to u in a pdf format, you can either have the document faxed, just scanned and sent back to u for record keeping & have it to make copies... this is amazing. and the best thing is that it is free, & the developers advised that it will remain free. the only negative side to it is that they request u use a 2.0+ mp camera, but i think the camera on the ppc is amazing so i don't think it'll be a problem... here is the link
