I've used it and to be honest, it's not faster. It does have kinetic scrolling and some good ideas, but they have only released the first version and that is slower than the current microb (at least the diablo microb - haven't been using chinook for a long time). The test they are referring to is actually a javascript test mainly. Anyway, I'm sure they'll be able to get it to a really good speeds soon, but for now, it's not better than microb.
