Universal UI as in no matter what program you are in, you get to the settings the same way. No matter where you are in the OS, the text fields respond the same way. That is universal UI. To even bring up TellMe as a response to Androids feature is ridiculous.

Works in ANY text field in ANY program. Universal throughout the OS.
XBMC is Xbox Media Center. Yea, Xbox as in MICROSOFT.
You may be right that Windows Mobile is a more complete OS, but its a complete OS that has basically made zero changes from YEARS ago, and its a dead platform. From the very limited amount I have used Android, it looks to be a great successor to Windows Mobile. Hope they port android to the TP2, as I don't feel like leaving sero anytime soon.
