The new Wii browser
Nintendo just released the "internet channel" for the Wii. It's based on Opera, and uses an onscreen keyboard for text input. Thank goodness for predictive text or this could take for freaking ever.
It does seem to work on most sites; nothing has yet thrown up any flags for me. They apparently spent a lot of time making sure YouTube would work in it.
It is the "trial" version, better known as "Beta" until March when the full version should be released. It will be free to download until June, and will then cost $5 to download.
I hope they get USB keyboard support soon, cause this gets old fast.
