Android as a mass-market, Google-supported and actively sold and marketed product, accepted by mainstream industry is on borrowed time.
Don't think Linux. Think Open Solaris. How much of a dent is Open Solaris putting in the server room these days?
How about MeeGo? Hell, even WebOS is still being developed by a die-hard core after it was released to the world as open source abandonware. How many MeeGo or WebOS handsets you seen at the Verizon store? Android lives as long as Google and Samsung pour money and manpower into it. After that's gone, it's a hobby OS for die-hards and niche hardware companies.
And when ChromeOS matures, Android =will= be abandoned. Get used to the idea. It's a transitional system to get to the ChromeOS/Glass ecosystem Google has been saying VERY LOUDLY is their corporate direction.
Why is this notion a surprise?
(No, they don't expect everyone to wear the stupid headset. Does Google seem stupid to you? What did you =think= their goal for "ubiquitous computing" was? Everybody going gargoyle? No. Cheap phones have cameras and displays, all you need for augmented reality apps. Glass will be perfect for low-spec, low-buck locked-down featurephones currently ruled by various flavors of Java.)
