Podcast: SCO's nosedive, XenSource's new home, Twitter and more...

We also analyze the acquisition this week of XenSource by Citrix for $500 million, VMware's rocketing IPO and how it all impact Microsoft's virtualization and hypervisor plans.

In addition, we talked about the greening of datacenters and utility computing, and David explains why he thinks Twitter and its 140 characters presents a challenge to Bloomberg's financial news and data service, or even Reuters and Dow Jones. I'm not convinced.
