iOS App to Manage all your documents
If you are relying on iPhone / iPad to manage your documents which can be an excel spreadsheet, a word document or even pdf files then you will need a very strong application for your iOS device. I have been using GoodReader for some time now and I am really happy with it. I have this on my iPad and it makes very easy for me to read email attachments, edit it and even send it back to my clients. I can even transfer files from my PC, Mac. Other biggest advantage is that I can even access my files in Google Docs and even Dropbox.
You can write notes on PDF files, which is a very useful feature which I really use a lot for my meetings.

Connect to all your cloud accounts like Google Docs, Dropbox, box.net or even an FTP server.
Goodreader is available for iPad as well as iPhone.
