Considering the Open Concept Layout

Now that hubby and I are not longer spending every spare moment wedding planning, we are finally thinking about improvements that we'd like to make to our home.  Our house it a 50s rambler, and while it doesn't have the bones these amazing spaces do, we are still thinking about knocking down some walls to create a more open and modern space. 
Loving almost everything about this.

Has anyone here remodeled for a more open layout?  Were you happy with the results?
