I wish David Allen Co would take the plunge and develop its own app / software, though I know that's a very different business from your primary focus.
Keep many of my day-to-day lists in Google Tasks since I use google mail as my primary email and its the easiest way to track and links with Google calendar. I use a google doc spreadsheet for projects and other higher levels lists as well as my lists for individual people.
For me it works great for work and a bit less well for home but am working on that.

Have been trying out IQTELL for a couple of months. It's web based and really configurable. So it can be as complex or as simple as you need it to be. I'm really enjoying it.
I need the easiest format for a GTD app as I'm forgetful, can't focus, easily distracted and new to the system. What is suggested for a beginner?
I clicked on Things above
But I also use that in combination with Pocket Informant on my iPhone
I use Pocket Informant for the calendar and contacts and Things for my next actions.
I use Evernote as my main GTD system now and, once I got to the 4th or 5th configuration, I've that it is perfect for on the go as well.
