The thing is, though, that they're bound to be getting good money from Sun, HP/Compaq, and IBM from licensing Unix (and a little from SGI). If they are looking to get bought by IBM, I think that's a bad thing for Unix, as it might then become possible for IBM to start leveraging that ownership against Sun and HP (and SGI). And since IBM has the least usable (IMO) Unix variant, that would be an exceptionally bad thing.

(Note that for the purposes of this post, Unix does not include Linux.)
