I'm in the midst of my Pocket Day trial and like it very much, and expect good things from PDLists. Right now I'm also demoing ToDo Matrix, which is also very well done, albeit pricey. If they can deliver a desktop/web component that is serviceable, I'd be inclined to go with TDM over PDL (in the absence of a web/desktop component for PDL).

Back on topic, however - has anyone bought NextActionGTD? How could this software claim to use the BB databases, when porgrammers with evidently much more experience have said that RIM needs to make them more accessible for that to be possible. Seems fishy, huh?
