Thank you people, there's been some interesting answers here!!
I like to consider how other people keep their 'stuff' together to see if there are programs I don't know about and also to identify new ways to catalogue or maintain my info etc.
Since I started using Evernote last year sometime I've become to use it more and more frequently as my major information repository for pretty much anything that I think I may need in the future.
The advantage is that it syncs across all my platforms so I can refer to it or add to it as and when required.
One Note from memory is not cloud based, but local to each computer?
