The Xbox 360 does it, and so does the PS3. But the Nintendo Wii seemed stubbornly stuck in the past, with no Internet media-streaming capabilities at all. Now Nintendo's promising Netflix streaming, but you have to wait until spring for that, and you'll need a Netflix disc.
But why wait? If you're willing to drop a one-time $40 fee, you can get Netflix, Hulu and more streaming on your Wii, without a disc, today. It's all thanks to PlayOn.
