Which is exactly my point. One of the most basic business functions, reviewing, editing and commenting on documents is not supported. I imagine your work around involved your colleagues having to create and send you a PDF which you then annotated and then someone had to sit down and transcribe your annotations into the document. If you had all been using iPads you simply couldn't have done it. And iTunes is not a business tool for getting files on and off an iPad. Yes, there are third party apps like Dropbox and GoodReader, but the basic supplied tool, iTunes, is an entertainment package, not a business one. How are you doing for monitoring and updating your project plan too or does that involved someone transcribing your changes for you too?
