My father has used Family Tree Maker for years, but hasn't upgraded since version 11.

It is difficult to tell from reviews at Amazon and other places whether upgrading to FTM 2011 is a good choice. File incompatibilities and upgrade woes sound like customer service is lacking, and i've read reports of it uploading your data to their database but then trying to sell you a download of data. Looking at the ancestry.com site makes me think it's solely about selling add-ons and upgrades. On the other hand, the feature set seems fairly rich and the software has a pretty strong following.

I was able to get Gramps working on my system, but that's not going to work for my dad.

Any advice on a good upgrade path? Doesn't necessarily have to be FTM. The only requirement is a way to import his existing data.
