Nintendo revealed that Wii's various controllers would be available to buy separately at launch. The Wii remote will cost $39.99; the nunchuck $19.99 and the classic controller about $20.
A little steep, $60 for the full function controller.

Anyone know anything about the "Classic controller"? I haven't seen anything on it.
[edit again] Nevermind, I've already seen it before, but thought it was just some random guy's concept art. Looks like I was wrong:

In addition, the Opera browser will be available for the system, enabling users to access the web with the console.

One of the channels available on Wii is called the "Mii Channel." Here, players can customize avatars by selecting from a variety of face shapes, hair styles, color schemes, and so on. The hook is that these avatars can not only be stored on the console itself, they can also be transferred to the Wii remote itself -- presumably so players can easily access their personalized characters and take them with them when playing against friends.
Another unnecessary, but cool feature.
It's definitely the cheapest of next-gen consoles, but to have to drop an extra $180 so four people can play makes me have some reservations. I'm not THAT rich.
