Someone on the Dell forums asked about the WM2003 upgrade for the X5. We all know of course that Dell discontinued that upgrade in the US a long time ago. Well, this naive person didn't believe Dell-Rollie's answer and just went ahead and naively searched Dell's web site for the upgrade.
And found it!

Looks like it is available for purchase again. Well, at least the website shows it. Hopefully it is not just a glitch with the database.
What a surprise!
