I sense a bubble.
Does that include the "n"-word? It is South Carolina.
My point is, whom does it have to offend to be profane?
1. Price comparison - Aim this at the barcode in store, and have it search Newegg/Amazon/whatever immediately for comparable prices.
2. Preview content - play clips from songs while you look at CDs or display a trailer for a movie
3. Magazines - aim at the Economist (or Seventeen or whatever) and get links to similar online content
4. Compatibility - Point at a wireless network product and see what technology it runs. Point at a motherboard and see if your current hard drive format is supported.
If they open the API, then there will be endless possibilities.
And for your CueCat haters, it didn't work because 1. It wasn't mobile, 2. Hardly anyone supported it and 3. They didn't want anyone using it for what it wasn't "officially" designated. Solve these problems on MS Tag and you'll have an awesome service.
