The web can be used to do almost anything these days
Edit images...
Make Mindmaps...
Plan the week...
To do lists...
Notetaking...
No need for paper. Don't need to worry about losing your USB. Don't need to carry heavy files full of notes everywhere. Seriously if the Internet fails one day (an undersea optic fibre cable snaps somewhere in the middle of the Pacific Ocean) I won't need to do ANYTHING.
