Check out LinuxInsider's article on Solaris 10. In particular, the last paragraph has high praise for Solaris 10 and Sun's forthcoming hardware ventures:
Bring them together in production systems and what do you get? The ability to organize your business around a single physical computer redundantly implemented in processors spread across your network -- meaning that a lot of business processes now limited by technology costs and software complexity can be simplified right down to affordability. That's what Solaris 10 is really about, and the 10-year impact is likely to be like nothing we've seen before.
Come Monday, I hope to see similar thoughtful analysis coming from other publications.
