Do you happen to have a full list of device type? We currently don't have a device classification like 'chromebook', 'chromebit'... We only have some available attributes to help determine which device type it is. We may need to create a new classification for this, so a full list will be needed.     

@morsed: Sorry, @rkc pointed me to the place where we have the device type info. It has five values: Chromebox / Chromebase / Chromebit / Chromebook / Unknown. I'll use that directly.

The following revision refers to this bug:

ChromeOS: Expose 'device type' signal

For use by the Get Help app, similar to how the 'playstore status' and
'managed device' were added recently. If the device type is 'unknown',
return 'chromedevice' instead, otherwise return the device type unchanged.
