Re: Wow apologists/deniers are out in force
They have stated "there's no plan to phase out Chrome OS". That's more than updating current devices.
The install base of android is irrelevant. If they create a single OS for laptops and phones which can run Android apps then they can roll it out to the android install base on new devices or as upgrades. This is basically what they did between Gingerbread and Ice Cream Sandwich. They already have an android runtime for Chrome, so it's a fair bet that this could be on the cards.
OEM apps are not related to fragmentations, OEM skins are. They can preload their own stuff onto a non-skinned Google Android phone and have zero fragmentation issues.
