In the long run, I think Natal will be more successful in the PC space than in the console space. Natal seems like an interface that can be utilized best for things like menus, browers, and whatnot. Just like the DS's touchscreen is only useful for some types of games, but it works great in the menu of every DS game, and touchscreens are also widely used outside of gaming. Natal integrated into a Windows interface would be cool.
However, I also believe Natal-like devices won't become truly successful until they're used alongside some sort of peripheral, like the gloves worn by Tom Cruise in Minority Report (which contain tiny LEDs in the fingertips, which I suppose is more similar to Move than Natal). I actually think the limited accuracy of Natal will hold it back in the near term, limiting it to experiences like Richochet at first. Without at least accurate finger tracking, I don't think it'll be feasible to integrate Natal into something like Windows at this point in time. I think the technology that Natal demonstrates is definitely in the early stages, and it won't be truly successful until it gets its Wii Motion Plus in a few years.
