Nova and Apex are one of the most popular android launchers. But they are quite heavy for the low-end devices. A member of Xda has made a launcher which is not only fast but elegant also.

                          

SlickSky is not like any traditional launcher. It is a minimal launcher with no app icons in the dock like the others. Homescreens are also limited. Swiping left or right will get you to calender or weather widget but you can customize it according to your taste.

If you want a fast yet cool android launcher that is not RAM hungry then you should definitely give it a try.
