i came across this very neat online to-do list

http://www.gqueues.com/

i was with RTM before, just made the switch although RTM synced very well with BB's, GQes's interface is awesome
I've tried a lot of productivity apps and various systems (GTD, etc) without success.
Pen and paper and a calendar seem to do the trick for now.
I rely on sticky notes and a pen, very useful especially when I stick them on annoying places like the laptop's keypad (never forget a thing). All electronic forms of to-do-lists and productivity apps were not successful with me either.
I don't think GQueues is a personal organization system. It is obviously aimed at collaboration. As soon as you're not alone in the team, pen and paper are the worst organizational tools of all time.

The product seems to go well with the gmail/calendar interface, and has a big bad "share" button in it. I feel like they're doing a dumbed down version of Wave.

It looks cool.
