I did as you said Oliver and downloaded the GTD Outlook set-up Guide!!
As the title suggests I did as you suggested and downloaded the Outlook (2010) GTD set-up Guide. (I originally set it up on my home computer but it wouldn't sync over to my BlackBerry Torch phone due to a yahoo connection error : ( so in the end set it up on the work computer).
It is only early days yet but after using it for the first time today I have to admit that it has helped me to be more organised for the day. I like the idea of organising it based on contexts and also being computer based which means that if I require any information I can simply bring up the particular category that I need and print it off - or sync to my BlackBerry - which I can do on the work computer.
I will report back in a month or so to let yous know how I am going with it but yeah so far it is a winner (especially when you consider that I was using paper and had to write out my daily list either the day before or in the morning of the next work day - very tedious work indeed). The GTD system through Outlook is definitely a great time-saver!!
