There's a good chance that the traditional keyboard layout isn't optimal. Maybe there's another layout that would suit you and your hands better. The Advantage hopes you'll try it.
The problem? It's insane looking and is $300. Personally, if I were to try a weird new type of keyboard, I wouldn't want to make a $300 gamble on it, especially when it looks like something that definitely would not feel right. But hey, maybe you're bolder than I am.
