To-Do, Is tech even needed?

So I was on LifeHacker and saw a recent post mentioning a sticky note program called “Hott Notes” (http://lifehacker.com/358564/make-and-take-your-sticky-notes-with-hott-notes) which seems like a very productive little app. Its your basic sticky note program with lots of little graphical and optional details you can tweak and change. Until now, I’ve been using the tried and true “ToDo.txt” method and that’s working just fine. But for now I’ll be giving this a whirl.

So my question to you is, do you use to-do list programs (online, windows, or mac) and why? Or, do you feel its better to stick to the old .txt file? Obviously we all have our own thing that works for us, but its always fun to see what’s out there. For example, if they had a sticky note program that allowed you to send things to gcal or have an alarm (probably is one there already!) I’m sure many would find that really useful!

The larger question implied here I guess is: Do we really need these technical options? Is it worth installing and testing programs to do the same thing a .txt file does with a few extra bells and whistles? In the real world, it’s easy to adapt to a low tech and direct hipster pda, but on the computer, you have many tempting free options… do you buy in?
