All the same, it would be nice if the dongle worked wouldn't it
Fair point. They should.
In my view there is little doubt however that Google is fully committed to getting their hardware strategy right. Simply viewing their Google Play Store devices website or walking into a Google Store within a store such as at PCW Tottenham Court Road provides ample evidence of how far they have come in a relatively short period of time: Pixel phones, Pixelbook, Pixel Buds, Nest Thermostats and cameras and soon doorbell, Google Home (and Mini and Max), etc.
Further, I read today that following success at 12 pop up stores in India, Google is planning to open their own stores in India in 2018, according to zdnet.com. I doubt Google would be opening its own stores (like Apple) if it were not fully committed to hardware.
