Apple Thoughts: Desktop Tower Defense Coming to the iPhone!

"The other big news they had for iPhone gamers was that the massively popular Desktop Tower Defense flash game is coming to the iPhone. Fuel Games is working closely with Paul Preece of Handdrawn Games to bring this classic to the iPhone. While iPhone-only gamers may have been introduced to the Tower Defense genre through Fieldrunners, for a large number of people Desktop Tower Defense was the game that brought it to the masses."

Often imitated, but never duplicated, I've yet to find a clone of DTD that's worthy of the original which, if you haven't played it, is one of the funnest Flash games ever. Since we'll probably have a bit of a wait, though, have any of you found any worthwhile clones yet?
