Multitouch is pretty cool technology, no question about that. And for awhile there, many folks such as myself were feeling pretty skeptical as to whether or not we would ever be enjoying this technology on the Linux desktop.

As you can see from the above linked article, everything you need is fully accessible. Now I would point out that this is still very much in development and this is not something that is really set for the casual users just yet. But as a proof of the technology working, I think we have arrived.
