Weby, you may be right that Dell is positioning with 1.1 before full scale deployment with 1.2. In their communication to enterprise customers they're still keeping their plans pretty close to the vest.
Nevertheless, their timing on entering the market could also have been determined by their interest in federal government business, particularly DoD, now that IBM has sold out to the Chinese. I believe gov't business was the primary reason Dell decided to launch their TC offerings.
