They are, but you really have to have it positioned right. If it's vertical and in front of you, it won't be useful, but if it's laid back at a ~45 degree angle, it becomes much more comfortable to work with.
However, I wouldn't consider it useful unless it's a multi-touch screen that Windows actually sees as a touchscreen. That opens up a lot of really cool ways to navigate your OS. A single point kit that is essentially another mouse isn't very useful at all, IMO, unless you're using it for presentations or something, like a Smartboard.
