I gotta say that this change makes me feel a little funny. I use Android after switching from an iPhone, I like Android and I like the menu button. Further, I understand that there are relatively few ways to do what needs to be done to support application options. Further, further, I understand that Apple and Android have blatantly lifted bits from each other. But isn't this a near pixel-perfect copy of iOS's options buttons? I was kinda happy when iOS stole Android's notifications behavior because I could feel a little superior for using Android. Now they're stolen something else from iOS, I feel a little less superior.
And I realize these are big mean companies, but still I can root for one of them...
