microsoft's agressive campaign against vmware
Colin Steele over at the Techtarget blogs tweeted, then blogged about the shenanigans Microsoft was pulling at VMWorld. They were giving away $1 poker chips that advertised http://www.vmwarecostswaytoomuch.com/.
I actually prefer Citrix’s way of addressing the competition. They added 130 new features to XenServer 5 to compete at a technical level with ESX server.
