FTM 2011: Are there Software Differences Between Essentials, Deluxe, Platinum?

I already have a membership in Ancestry.com.

I'm looking to change from The Master Genealogist SW (too steep a learning curve) to Family Tree Maker 2011.

Are the differences between the Essentials, Deluxe, and Platinum versions of FTM 2011 only in the length of time of the trial membership to Ancestry.com?

Thanks,

Wes
