I'm unrooted on a galaxy nexus, and I haven't bothered with launchers, and don't know much about them. My primary concern is speed, especially in multitasking. I have Swipe Pad and Folder Organizer and they help with that. My other desire is aesthetics of course. I like eye candy. But functionality comes first no matter what. It seems like I can't customize icons much without a launcher, so I want to consider getting one. I'm not savvy enough to go rooted, so what launchers would be best for me?
