I find Toodledo to be close to perfect, if not perfect, for GTD. If RTM only has tags to categorize your tasks, Toodledo has tags, context and projects/folders. Of course both have priorities.
But I’m starting to like Toodledo more because of its great iPad app and its integration with Nuevasync (to synchronize my tasks with my Windows Mobile phone).
Unfortunately, Toodledo has no native Desktop PC application. I’m not a programmer, much less a software developer, but now I’m wondering, if the developers could afford a great iPad app, why not develop one for Windows PC? If it’s Flash-based or will be running on Adobe Air, I wouldn’t mind. The most important thing here is it can be accessed offline and seamless synchronization with the web service once you get online.
I know there’s Task Angel, but that you have to pay quite a hefty amount in order to use it. And it’s not native. It was not built to integrate with Toodledo alone. And it lacks Notebook support too. I’m really talking about an iPad-like application.
Hope the developers consider my request in the future.
