The Netflix discs enabling streaming video over the Wii are already in the mail and one reader's uploaded this video, showing us what we can expect - in this case, 30 second loading times to browse the catalog.
By this video, booting up the service takes 33 seconds. After registering the device, it's another 33 to get to the video menu. You'll also notice some 10 second waits while the console downloads other categories for browsing.
Of course, maybe this guy has a slow connection or there's something else at work here. And yeah, it's only 30 seconds. But watching it play out on a video (with no audio) it seems twice as interminable as a 30-second stoplight, which itself seems infuriatingly long when you're in a hurry.
