Things is helping me Get Things Done
CultureCode’s fantastic task management application Things is something I have been looking long and hard for, it isn’t complicated and it has a lot of great features to help you do stuff! This combined with Inbox Zero is helping increase my daily productivity.
Things is currently in Preview status (Alpha) and a final version will be released this Spring for what I feel is a little pricy $49. If you sign up to their newsletter before the end of January you will receive a 20% discount.
