On the other, as a Windows desktop person I can't live without Home/End/PgUp/Pgdown, and in different combinations with Shift/Control. That's one of reason I can't fully enjoy MacBook, not to mention the incredible fact that it doesn't have a Delete key. No, it's not the same that you can use modifier key with backspace, modifier keys are used for extra functionality, i.e. to delete to begining or end of the word, etc.
