Where does Sun go from here?........How do the differentiate themselves from every other x86-64 system out there?
What other Opteron systems out there? IBM's is essentially a cluster of 2-way workstations. Opteron on Solaris in larger SMP systems would be a unique offering. Going to standard hardware and software, Linux and Windows, means they're just another vendor and they don't have experience competing on price in a commodity market.
