Parent article: Solaris 10

In physics, momentum is the product of mass and velocity. So the installed base of Solaris, its "mass", is indeed crucial to the question of whether Solaris has more momentum. But just as crucial is its "velocity". How big is the Solaris installed base compared to last year? Probably about the same size. Compared to five years ago? It might have been bigger then, at the height of the boom.

Linux's installed base is indeed smaller, but it's bigger this year than it was last year, and huge compared to what it was five years ago. That "velocity" can give it the higher momentum, and I think it does.

You seem to be taking rate of growth as velocity. That ruins the analogy, because in physics, velocity isn't the rate at which the mass in increasing.

I don't see any way to break down OS momentum into analogies of mass and velocity.

But I don't think rate of growth is any part of an OS' momentum. Momentum is the tendency of a moving object to keep moving. An object with great momentum doesn't speed up or get larger. It just doesn't come to rest easily.

I see Solaris as having great momentum. Longtime users give an OS momentum. I can't tell how much momentum Linux has. New users are often easily switched to something else.

Now, black holes and OSes, there's an analogy. ;-)
