I came across this post today – great because it summarises a heap of useful tools all designed to help you remember things, many of the tools I use daily and my favourite is probably evernote. The post also offers some tips on the best way to create notes  – a good read check it out

As I travel frequently and always need access to my files – I carry around a portable hard disk, however there have been occassions when it has failed, or worse I could have lost it. I have found and started to use some of these online tools which make them readily available as long as I have an internet connection available.

• Drop box - I really like this to share between my 3 computers
• Mozy - online back up
• Google Docs – I use this word docs and excel so that peopl that I work with in Canada and Australia can access the same files ( and its free)
• Zoho has a heap of online collaboration tools thatyou may find useful
