With Android management shakeup, Google reveals the broad sweep of its ambition

I can think of two more salient differences:
1. Both systems are based on the Linux kernel, but Android is based on a custom libc (Bionic) and various Android-specific things (like SurfaceFlinger and AudioFlinger) held together by an Android-specific IPC system called Binder. By contrast, Chrome OS is much closer to a typical GNU/Linux stack; in particular, AFAIK, it's based on X11 and GTK.
2. Android supports persistent on-device storage, whereas Chrome OS only supports ephemeral storage.
With NaCl, HTML5 audio and so on you can just obsolete Android after a while...
More or less, Android = Samsung. No matter what Google thinks, Samsung has their own agenda (as they should) and dozens of billions ready to be put to play. They can fork it in a year or two and take it from there.
What they won't do is move to a new Samsung phone that doesn't run their existing apps.
Furthermore Samsung isn't in the software business, its in the hardware business. Unless they find some giant profitable reason to fork and diversify into becoming a software business also, I see no reason why they would not simply keep riding the innovation coming out of google.
2 years back, it was a smaller and different market. Samsung has established brand now and has more power on android. They are moving around 100 million phones a year now. It's not the same market. Samsung doesn't need to do much to fork android. They recently announced a new wallet API for Samsung devices. If developer start doing apps for Samsung specific API and devices that's all they need. If those become popular enough that's a huge barrier for other OEM's to copy.
Few years back google forced Motorola from using a competing maps service. I don't think they can force Samsung from using or creating non google services.

What happened to Apple and maps? Nothing, a bunch of bloggers were pissed, iPhones still selling like hot cakes, Samsung did their part but still. Now Apple has their maps and all data goes to Apple, not Google. Soon enough they'll get better, meaning Google loses. It's in Google's interests and they'll pay to have Apple, and Samsung to run Google Search and other G apps. But would you develop if Samsung Galaxy was out of "Android" ? Only time will tell.
Look how iPhone vs. Android sentiment changed over time.
At first the majority opinion was that Android was capable but slow and unpolished.
Around 4.0, the majority opinion was that Android was getting closer to iPhone but not quite there.
The most recent sentiments are: Android is starting to outclass iPhone in some important areas (Maps, Google Now).
Obviously, it won't suddenly cause everyone to stop buying iPhones and start buying Androids, but if things continue, the tide will turn.
Simply stated: Google is out-executing Apple on software. Press, bloggers and everyone else are noticing that and people do care about what The Verge writes or that people like MG Siegler go from "Android is crap" to "Android is really, really good".
So yes, things like Maps and Google Now are important and hard to re-create by a company like Samsung (or any company, period). That keeps Samsung (at least for now) from forking Android and trying to squeeze even more revenue out of it for themselves.
Google's future control of Android will depend on how many important and hard-to-recreate pieces they can implement, and given that they are cloud services company first, they are well positioned to execute on that.
