GTD Outlook Plug-in best choice for Outlook Users?

[Serene]

Hi Everyone,

I am new and would like to use Outlook (synching to my windows PDA) as the core of my GTD system and have a question to ask for those more experienced:

Is the GTD outlook plug-in the best software in your opinion for Outlook users implementing GTD, or have you found more effective ways such as using Outlook for Email, but keeping your project/tasks list in another note based software?

If you use another software for your lists/tasks/other features, please state what software you found was best and what system you created?

I noticed people on the forum using other software programs along with Outlook, however I don't see why this is necessary since outlook with the plug-in looks like it solves everything...

Thanks!

Serene
