Totally agree. For one, the home buttons on iDevices have proven to one of the components with the shortest life (I've worn out a 3GS button before multitasking even came along). My iPad button is showing signs of wear after 5 months. Gestures at least allow you to press that button less. Also, there have been usability concerns for the less able bodied. A double click is not always an easy action for certain types of disability, although I am the first to concede that a four / five finger gesture could be equally as challenging in some cases... That said, having choice is where I like to position myself. There is absolutely no harm in having the choice there. If you like it, use it, if not, ignore it.
