I am in my 50's and until 2011, had never done my own taxes. But I bought TurboTax and struck out on my own....I am so glad I did! I learned a lot, and when I got stuck, I just called the Turbo Tax help line and always got the help I needed, even if they had to transfer me to someone else. I have found their representatives to be extremely helpful and patient.
What's great about it: Easy to follow; questions are in English, Help is just a phone call away!
What's not so great: None - other than its association with taxes.
Perhaps my return was more challenging this year, or maybe I am getting slower, but the decision where to include what., and what to include was not as clear as in past years, and I have been using Turbo Tax since 2008.
