The Inquirer about Niagara 2
The Inquirer published a long article about the technology in Niagara 2 aka UltraSPARC T2. The article is much more positive as the concluding paragraph would suggest.
It looks like Sun delivered on what it set out to do. The shortcomings of Niagara were addressed in Niagara 2, and a lot of interesting features were added. Sun is positioning N2 as a network facing chip, not a back end number cruncher, and it looks to be able to fill that role with far fewer caveats than it's predecessor.
