I've been using OF and Things for about a month now and wanted to offer up some points of interest to anyone debating the purchase of these two apps. It's hard to go wrong here but both do have some current limitations and they are very different in their approach to GTD and task management. Here is a quick look at the iphone versions of these two apps: Price (an important factor) Things Touch is $9.99 for now and according to the developers will go up as more features are implemented. Things Desktop is in preview stage and is free until version 1.0 comes out which is an unknown at this point. Things will cost $49.99 and $39.99 for subscribers of the newsletter. OmniFocus is $19.99 on the iphone and has 3 different price points for the desktop version. $79.99 retail, $59.99 for registered users of Omnioutliner Pro, and $49.99 for students, teachers, faculty, professors, etc. (basically an educator discount). On the Iphone: Here are some bullet points to consider TT now syncs via wifi and this feature is very fast. You basically get on the same network and open both programs. Things desktop will pair your iphone to the desktop (kind of like a bluetooth pairing) and syncing will then be automatic as long as you are on the the same network and both programs are open. Like I said, this syncing is very quick and so fas accurate. OF syncs via Webdav which means you need a Mobile Me account. This will enable syncing to Mobile Me anywhere your Iphone has an internet connection. Syncing speed has improved dramatically from 1.0 to 1.0.3 but is still nowhere near as fast as Things. i have found the syncing reliable on OF. There are two key liabilities to each Iphone version. Things does not support (although it is coming) two of the best features of the desktop version Areas of Responsibility and Tags. This leads to the 2nd liability which is that tasks within your AOR will sync and appear on the Today screen and next screen as a jumbled mess of tasks with no association to a project, area, or tag. It creates a mess on both Today and Next screens. If you are looking at focus as a key driver in your purchase then forget this for now. The downfall of OF Touch is that it does not have a today view (maybe a personal preference?) and it is very slow to open and sync. If quickly opening and entering a task on the go is a priority for you then OF will cause frustration. The highlights: OF Touch supports the key features of the desktop version. It supports contexts, location awareness, sub projects, flags, due dates, folders, etc. Without a today view you will have to use a system that allows you to focus on whatever is important on that particular day. It will sync all these features back and forth. OF is very strong if you want to focus on certain areas of your life (work, home, hobbies). TT is fast and simple. It has a great today view (marred for now by the clutter caused by its lack of support for areas and tags) and a next action view. It is quick to open and enter tasks into the inbox and is easy to setup scheduled tasks and projects. TT is also very stable and has been since day one. I have gone with OF because I like the way it allows you to focus in on specific areas of your life better than Things. Both are great programs especially for such early versions.
