The Wii remote and Nunchuck attatchment are useful for different types of gameplay; Zelda, Metroid and other shoot 'em ups, and some sports titles. But there is a limitation to the games which can use this revolutionary controller. Racing games may find the remote challenging to use, or fighting games for example. However, this does not mean they won't find a way to somehow get these games on the console! The Classic controller will most likely be used for these sorts of games, like the already announced Super Smash Bros. Brawl.
In my view, I think the controllers look like fun, but also consider the classic controller more practical and easy to pick up and play.
