To-Do Ta-Da
There are a lot of to-do lists out there, and it is usually cited as one of the missing features in the native iPhone app list. Thought I guess you could use the notepad as a to-do list.
The 3rd-party one I hear the most about is Ta-Da List. However, it seems overly complicated to me. Even the sign-up requires too much. With the way iPhone cookies work in Safari, you should just be able to sign up without entering any info at all. I’d love it the to-do lists worked the same way voicemail or email worked on the iPhone — just a list and not much more. I’m tempted to create my own To-Do list app, but I’m thinking this will be a native feature before too long, so there’s no point.
