That's exactly what I thought. At my university we were equipped with a bunch of Ultra60s that were upgraded from Solaris 7 to 8, from 8 to 9, and finally from 9 to 10. None of these upgrades slowed them down in any way, at least not that I noticed (they did get memory upgrades however). Now I could understand if Oracle dropped support for the Ultra60 with Solaris 11, but for a Blade2000 or Ultra45, which may be just a couple of years old? That's a surprise. I have an Ultra45 myself and I'm not at all happy with this, especially since Solaris 11 Express looked quite promising on the machine.
