IBM to NOT upgrade to Vista ?

Dec Pointed me at this article:

"Andreas Pleschek also told that IBM has cancelled their contract with Microsoft as of October this year. That means that IBM will not use Windows Vista for their desktops. Beginning from July, IBM employees will begin using IBM Workplace on their new, Red Hat-based platform. Not all at once - some will keep using their present Windows versions for a while. But none will upgrade to Vista."
Interesting. Looks like Big Blue is putting is money where its mouth is.. I wonder how far this has spread within IBM - and why they're not shouting about this from the rooftops ?
