The one you love to use, enjoy working with, handles all the basics and will use every day multiple times a day without fail.So I am wondering what is the best device to use the GTD methodology.
I would love to hear your thoughts.
Yes, @yoha, I agree with @Oogiem ! Implement GTD using the hardware that you have and like. Don't treat GTD as a reason to buy a new shiny gadget.The one you love to use, enjoy working with, handles all the basics and will use every day multiple times a day without fail.
It can be a notebook, tablet, 3x5 cards, post it notes, laptop, phone or many other things but the key is the methods not the tools. Pick tools you like and spend your effort learning the methodology.
