Im interested in purchasing an Ipad but I plan to use it for viewing my text books. I've purchased chapters from cengagebrain(ichapters) but it sends it to you as a spdf which is sealed and allows limited access to the file. You can't print,save nor edit the file. Ive tried printing it to oneNote2007, creating a pdf printer and also trying to get the .spl file but still no luck. Maybe I'm doing something wrong I wanted to know if anyone else has been able to successfully convert a spdf file into pdf and view it on the ipad?????
