Paul, further to my comment (btw thanks for the mention), IBM believes and support open standards and also encourage choice for its almost half a million employees. Regarding open standards, we are encouraged to use either IBM's own Lotus Symphony or OpenOffice as a “Office” application. When it comes to operating systems, we have a choice between Linux (we have internal versions of Ubuntu, Fedora, OpenSuse and RedHat) … I run Ubuntu and also have both Chrome and Firefox on my desktop — this comment just happens to be posted from Chrome.

And we even have our equivalent to Twitter called BlueTwit (yes, I also laughed at the name the first time) and an internal Faceboook called BluePages.
