it has been pretty smooth and quick for most things, but some things it isnt on, like for example, i logged into my hotmail account and was checking my emails, but then it froze, i had to reboot the wii and once i had done that, i can no longer get onto my hotmail inbox, it just wont even try to load it and freezes up as soon as you click login! other things are looking good though, went on the wii site and video playback through flash players worked (i watched the wii internet video to be ironic) but overall its looking good, a few bugs but its still early!
P.S this was posted from a pc, there was no way i was typing that out on a wii!
