Their "Informational website" is http://www.websphereloveswindows.com/ (Requires Silverlight, way to get to the non-MS audience there!)
Tidbits of information that they are touting include:
"The IBM configuration cost $260,128, while the HP-Microsoft-based set up cost $87,161 — about a third the cost of the IBM system. Beyond cost, however, Martin claims that the HP system also outperformed the IBM — with 11,000 transactions per second (tps) versus 8,000 tps on the Power"
Now we need to try to convince the business that this is just marketing buzz. How do we defend ourselves from these rather appealing MS numbers?
