GTDNext is the first app that has the flexibility to do most of what I need it to and the development team to implement the rest. In the short time I've used the product (12 months, one billing cycle, a lot cheaper than alternatives I've tried) I have seen great improvements to the visual appeal of the front-end, the workflows supported and even the data storage at the back-end driving performance.
This is my idea of a software project done right. We'll always want more features and new behaviors but so far the GTDNext team are doing a great job of prioritizing the work and delivering the most value first rather than going after kudos and cheers for features with no depth.
Well done guys!
