For those who try to decide if you want todomatrix or NEXTACTION for blackberry, I can tell you with my own experience of buying and trying out both applications, that todomatrix is vastly superior than NEXTACTION.

With NextAction! I feel I get nothing more than a category. You can't even see how many tasks within one category - you have to view all categories one by one! That is insane! Also they don't have due date or alert function. So to me, the NextAction! is un-usable, and at their price, it is not worth the money at all. So you are warned, don't waste your money on NextAction! I regret my purchase.

The only lack from todomatrix is that their development team is not good at keeping release promises and keep delaying the release. They say they focus on desktop add-on, so they even ignore all the feature suggestions and bugs report, no update in a long time. They do lose some customer confidence in this aspect, otherwise, it'll be perfect.
