Yeah, some launchers include it as a feature. They can do this as they are stand alone entities not affiliated with any manufacturer. Manufacturers such as Samsung, LG, Motorola, HTC, and etc. are not allowed to include it as part of their software by default. Like the rubber banding (bounce back) effect had to be removed because of crapple and their hideous lawsuits. Since though...a judge ruled that an invalid patent. So we'll see if the "bounce back" makes it's way back into android phones.
