I miss smart actions the most. I have read that Tasker will work in it's stead, however, the wife doesn't seem to agree when she gets jolted awake at 2:30 am from an email notification. I also don't care for the locked in place Google search bar. I hate that thing. Especially right at the top where I have to look at it.
But, in comparison to the RAZR Maxx, this one is so much nicer. Less lag, much less. Its so smooth and zippy. Best one I have had yet.
