Its inaccurate to call the Chrome OS a “mobile” operating system or compare it to Android, as much as calling the latest build Mac OS X Leopard 10.5 “mobile” against the iPhone.

The big division is 1) Form factor; where Android is for handsets and MIDs, and Chrome OS is for QWERTY netbooks 2) Connectivity; Android has a radio stack, Chrome doesn’t.

In the short term ( next five years ) phones and netbooks will remain distinct, but yes, ultimately the lines will get very blurry.

Looking ahead to when personal computing is completely ubiquitous and Redfly-esque terminals are everywhere, like public payphones used to be, ChromeOS will find itself well positioned.

Sit down at any library, restaurant, coffee shop, or wherever you’ve chosen to work at, and the surface style table prompt you with Chrome OS sign-in. After signing in all your preferences appear, your cloud storage is available, your social graph’s activities pop up.

And… A Google OS has mainstream brand appeal/recognition in a way Ubuntu Netbook Remix never will.
