That said, there is still a long way to go and this technology still has not found a compelling application. The only reason I would consider using it is to be one of the first people to actually figure it out on the ground and potentially find those compelling uses, if they exist.
Google has the classic big company/large install base edge in this area.

Apologies for my lack of reading-all-the-way-throughness
In any case, this will be a large space and there is room for multiple players.
apart from that being true, I believe Google's approach to location leaves open other opportunities.

Mixed feelings about this Google, mixed feelings indeed.
