Nexus S ICS Update... Clarity?

Some people at work have Nexus S phones. Last month in December Google announced those devices would get Android 4.0 (ICS) via an Over The Air (OTA) update. The guys at work are still waiting. Apparently with Android updates you just have to wait indefinitely until an update notification pops up and then you'll get to download the new software update. Such uncertainty would drive me nuts.

To illustrate "Android Clarity" just google for iPhone iOS 5 update. The very first result at iPhone's company website [ http://www.apple.com/ios/ ] explains how to do it. It says:

"Update to iOS 5. Just connect your device to your Mac or PC and follow the onscreen instructions in iTunes."

Now google Nexus S ICS update. All you get are lots of shady tech-blogs without real answers. No google.com page in sight. When I did the search the first link to google.com was the 17th result. It was a forum post from someone who was clearly very angry with how his update process had gone.

Google has stopped the OTA update in "certain regions" but they're not saying which regions. From searching around the Internet it seems everyone (read: a vocal minority) is having problems with Google's OTA ICS update on Nexus S phones.

Is anyone still getting ICS updates on Nexus S or has Google completely halted the rollout? And if you look around the Internet for what ICS is doing to your Nexus S, would you still want to update?
