Free....FREE....OMG opera is not free for "gadgets". Goto their website and you will see that they charge around $24 for most phones.
Their only going to charge $5 for the wii(500 points). $5....THATS IT.
Stop bitching, and pay the money if you want it. Otherwise, deal with the free trial version.
Also, browser software is not in any way trivial or simple. Its fairly complex and must be respected as such.
