Yea, the second one just didn't do some of the things the original did that I really liked. Plus I found it a little more difficult to use. One of my main gripes, in terms of features was that the second one didn't rotate when you rotated the phone (iPhone). I also thought the sliding panels to get to certain menus was more complicated than it needed to be. They basically traded a "click" for a slide. So rather than having dedicated buttons on the bottom of the screen you had to slide a panel or two panels over to get where you needed to go.
Anywho, harder to navigate than what? I forget android or iphone?
EDIT: Wow, someone actually reads my posts?
