I sort of disagree with this. IMO, "surprised" refers to a state of not being prepared, even more so than being merely flat-footed. I like to encourage scouting/good tactics on the PC's part. An enemy rushing from hidden ambush with a melee attack technically becomes visible the moment she leaves cover/concealment. I'd judge it a surprise round, however."Suprised" is a specific condition in which one, or many, members in a combat is unaware of an opposition at all. When they become aware and act in initiative order, they are no longer suprised nor are they flat-footed.

So if you dimension slide in the suprise round, or in the first round before they act, then you can deliver a sneak attack. Otherwise, no.
As for hiding, remember that you must have either cover or concealment to do so. When you move next to him, it is extremely unlikely that you have cover with regards to him, and if you have concealment, he will as well most likley, and you cannot sneak attack him. As soon as you appear next to him, you will no longer be hiding (because of no cover nor concealment), and no longer elligible for the "sneak attack from hiding" mechanic.

It's not because your invisibile.
Let's say you are not invisible but are simply starting a combat. What about that situation causes the opponent to lose their dex bonus. If you'd insist upon "flatfootedness" as the reason, I'd simply reword the question: what about flatfootedness causes the opponent to lose their dex bonus? Because the rules say so....
