For real, you sold me on that trackball. That sounds like the coolest feature a phone could have, right down to the multi-color led built in beneath it. I really really hope we see a return to something like that! Touch screens are very useful and have their place but physical buttons/controls are usually preferred when done properly. Here’s a pic of the Nexus 1, that trackball indeed appears to be cool as fuck:
