Hey, I'm a big fan of productivity tools, I love using them, I love trying new ones, I hate having to migrate all my stuff from one to another but I do it anyway from time to time because I get bored and want to try new things all the time.
Let's play a game. I'll give you 4 "roles" and you tell me what tool or tools you use for filling those roles. You can name the same tool in multiple roles. You can add comments on why you chose those tools, or not.
Role #1: To-Do's and Lists
Role #2: Note taking
Role #3: Time tracking
Role #4: Cloud sync and/or storage
I'll leave my choices (as of today at least) in the comments.
