I have a similar situation. I use OF on the ipad and the iphone, but have a windows machine at work.
This link will let you send actions to OF through the web and email. It isn't a complete no brainer but it works fairly well
I find that I don't mind the extra effort required to renter actions/projects or whatever into OF. I find that this helps make sure I process rather than just collect. I find that if a process becomes too seamless one can click away and fail to actually think about what it is you are looking at, and it can get dumped into a system by it isn't processed.
