[whatwg] API for unique identification of devices (mobile/tablet/pc)

[Stan]

Last thing to remember: the device ID is not something secret and forbidden for
native applications. For example, Android provides Android ID and iOS ASIdentifierManager,
which can be read by any installed application. Taking into consideration that many
web-services do provide native clients, they already know device IDs (if they want to).
Moving this property into browser will just simplify developing web-applications and
make them more competitive compared to native apps.

Best wishes,
Stan
