Swift To-Do List Lite is a great Desktop tool. The install is very simple. Just download the setup program and run it. There's nothing to it.
Using the application is extremely intuitive. There are keyboard shortcut, which is a huge advantage. Many web applications lack keyboard shortcuts, I love the keyboard and do my best to shun the mouse.
Even though the application is extremely easy to use and understand there is also a great online manual.
The best attribute of this application that I've found so far for this is that it can be used very easily by anyone. The professional version states that it has unlimited tasks and to do lists. I haven't hit the limit on tasks or To-Do lists yet. However, once I do, I'll probably be ready to upgrade to the professional version. By that point the application will be such an ingrained part of my routine that staying with it will be worth the price. Erin uses this on our home computer to make to-do lists for me, and her, as well as to keep track of what we need for our groceries.
I do have a few complaints. Everything is saved locally. This prevents online sharing between computers. I love the offline version, but being able to upload the list to a service and view all of my to-do items from wherever I have the application installed would be nice. I've also started trying to limit the applications that I use to applications that will run entirely on my USB drive. I will post more about these later. Having to install locally means that I have to have the computer that has my list on it with me in order to see what I have to do.
All in all this is a great application that I will continue to use at least until the limit of the free version is reached. There are too many benefits to replace it with something that I would have to pay for.
