Android: If you're an Android user who's keen on Google's Tasks to-do manager, a beta application can give you offline access and syncing to the tasks you've stashed away in Gmail, Google Calendar or iGoogle.
Google Tasks still has a ways to go in becoming a universally useful to-do manager, but if you've got a Google-syncing phone in your pocket, and can't quite swing the $US25/year for Remember the Milk's great app, it might just be the best task manager you'll actually use. gTasks beta is a really, really simple view at your tasks, offering the task name, notes and due date for each. You can manage your tasks offline and sync your changes to Google, and ... that's about it, for the moment. Then again, Google Tasks itself doesn't offer a whole lot more functionality, even in its Android-friendly mobile version.
gTasks Beta is a free download for Android phones with Google syncing (a.k.a. with the "Google Experience").
