I just got a Galaxy Nexus a couple days ago, and my first thought after turning it on was that I wasn't sure where I could touch to do things. They try to be so slick with the UI that it's hard to see the boundaries between UI elements some times, especially with editable text fields, which are just a bottom border---the background color isn't different and there are no other borders. Another example is going back in applications. There's the back button, which takes you to where you previously were, but then there's another button that seems to take you to the parent menu (at least in the Play store, not sure if it's true in all apps). The latter is easy to miss. I didn't notice it the first few times I opened the Play store, because the back button is the application icon. All they do is add a tiny grey arrow next to the application icon when you can use it to go to the parent screen. I'm used to it now, but it can probably be improved by installing an aftermarket firmware like CyanogenMod. I haven't looked into it.
