I have used 2011 since it came out, after resolving some installation issues. Then my laptop went out and I had to have everything wiped and reinstalled. In the meantime I received FTM 2012. When I got my laptop back, remembering the issues I had over about 3 months with FTM 2011, I was afraid to install 2012 as it states that if you do open your tree in it, you will be unable to open it in prior versions. Scary stuff when you consider all the problems.
The question I have is: Is it worth installing FTM 2012 or should I stick with FTM 2011? Bear in mind that I don't care about syncing with the online tree and will not use that.
