Solbebe, I just discovered the same thing: when I save a new Speed Dial link, it goes to the BOTTOM of the page!
I ABSOLUTELY HATE THIS!!! Now whenever I want to access a new Speed Dial link, I have to scroll all the way to the bottom of the page. This is a time-waster! Why can't Opera give USERS the choice to have new links at the top OR bottom of the page??!!
