Two features sorely lacking from iPhone are to-do lists and checklists. The Newton had both, and Address Book has to-do lists. Rumor has it that AB's to-do feature will be incorporated into iPhone's Mail.app (strange, why not Calendar?) when Leopard releases. At least Mac users who are in a position to buy and install Leopard have something to look forward to. I don't know what will happen on this front in the Windows world, nor whether Apple will leave Tiger users in the cold. In the mean time, I know there are web-based to-do "apps" and checklist "apps" but all of them that I've seen require one to create an account to use them. I have too many accounts as it is. I don't want more. I already have to-do's in AB and I don't want to have to duplicate them into another app and keep them in synch with each other.

This really is a bigger deal than it may sound. Checklists are vital for making sure all your gear is accounted for before (and after!) a location shoot, keeping track of the shots you want/need/intend to get, and so forth. To-do lists are great for noting which client's deliverables you need to work on if there's not a fixed deadline. I've found it can also be a convenient way of reminding myself of upcoming projects that clients have in the works but haven't yet scheduled. Sure, I have a Palm with both checklist and to-do apps on it that I could use or I could even (gasp!) carry a small paper notebook, but that would defeat the purpose of using iPhone as a convergence device. See my earlier posts if you don't know why that's important to me.
