Some people just don't get along with wires. I'm not fussed, they've never done anything to me personally, but I've also seen men boil over with rage just looking at a phone line.
So I can understand why stuff like this has not only been sorted out, but engineered and shifted to retail in under a month. It's a wireless Wii sensor bar, which will do everything your regular sensor bar does, only more conspicuously and at the cost of batteries.
For $25, you can probably do without one. Then again, some people have gaming rigs that look like an Escher painting, and this will come as welcome relief
