I have one of the panes of my Android phone launcher filled with icons for Google products. Finally getting on + meant I had to delete one to make space for the Google+ app icon.
It ultimately turned out to be an easy decision - I dumped Voice Search in the bin. Voice recognition, be it Google's or the ones companies use for their phone systems always seem to be an elaborate practical joke to me with their accuracy indistinguishable from picking random words. It never saves time or interaction. Everyone I ask says substantially the same thing, yet they must work for someone somewhere else why bother?
