The translation feature in the headphones is amazing, but I feel Google made a huge mistake to make that particular feature exclusive to the Pixel. By doing so, they are undermining their other hardware partners.
I think they will open it up in a few months, Google did the same with other exclusive features in the past.
Actually, the bigger problem here is that they're giving Samsung, Huawei, LG, and everyone else in their Android ecosystem a run for their money. I don't get the strategy here.
I think the problem is that these companies are fragmenting android too much, just look at Bixby. I don't think Google would be doing this is its partners were not trying to undermine Google. Microsoft had to do the same thing when they introduced the surface, someone has to provide the leadership and vision or else the competition will destroy them. The status quo has changed and Google is providing much-needed leadership to the Android ecosystem.
