OEMs and hardware buttons.
Google shows you the direction their taking Android and some of you(HTC and Samsung) still wish to do things your way.
Software keys may eat up screen, but at the times you really don't want them there....guess what? They go away.
I was visiting AndroidCentral a while ago and saw Samsungs version of Jelly Bean. They included Google Now without any changing it, yet they had to come up with a workaround for activating it.
On the Galaxy Nexus, it's a simple swipe up from the software keys. Nice and intuitive. On the SGS3? It's now a button included in the task switcher list.
Pitiful. Can't wait to see how HTC will implement Google Now.
Things like this simply disgust me. Why continue down a path that Google is leaving? I'm under the impression that soon, Google may even leave buttons completely in favor of gestures.
What then? Will these OEMs still practice the art of placing capacitive buttons on their devices?
Who else is ready for hardware buttons to leave and ready for a clean front on their device? The blank front of the Galaxy Nexus is wonderful.
