That's an iPhone feature. On Android you can do 3 quick swipes to scroll to the top or bottom of a page. Or you can install another browser. Dolphin HD is popular and has gestures, including one for jumping to the top of the page.
It's about the same on Android: long press the bookmark and the menu will have the option to add to home screen. If you have a third party launcher, you can probably change the icon too...
