Great to have you with us.
Great input..thanksi just performed the upgrade from Eos 1.0.0 to Eos 2.0.0 with the advised version of Gapps, and can confirm that You tube needs to be manually downloaded from the marketplace. also the contacts link within the Gapps folder on the homescreen does not work [states that contacts are not downloaded] but the contacts icon that comes with ICS 4.0.4 [or put there by Eos 2.0.0] on the home screen does work.
Great and welcome.the upgrade went very smoothly no problems at all, other than that.
thanks for all the work
Enjoy your Xoom
