Computer and Video Games got some nice screen shots of the Wii browser.

The article says you’ll need to pay for the opera browser after six months, but someone from NeoGaf contacted Opera to clarify this, and this is the answer he got:

For the first six months, Opera on Wii is free. If you download it during that
period, it is free forever. You will not have to pay again after the first six
months. It is only if you download it after the first six months that you will have
to pay a one-time fee for the browser.
