Hi, My dad just got an iPad. Previously in his work, he used to over dosens printed hard copies of emails a day. Simple things such as "approved" or "?" or circling things, and he would pass it on to some co-workers. I want to find him an app that would do the same, and simply. I want an app that allows to write HAND NOTES on received emails instantly, and reply them. I assume that the reply would be as an image file or pdf, which is fine. I know that there are a lot of ways to work around that, but because of the high volume of this process, it has to be as quick, simple and instant as possible. Any suggestions?
