I suppose you are referring to devices like the new Nexus 7 that come with Chrome pre-installed. It doesn't have android's native browser and as far as I know it's the only device that ships with Chrome.

Nope, it's basically any device with the Play Store on running Android 4.2 or later.

Chrome being the only browser on Nexus devices has become another reason to avoid Nexus devices, along with the Hangouts as only messaging app and the general lack of storage. It's merely that the alternatives are arguably worse.
